The PM100D is the cornerstone of Thorlabs' optical power and energy meter consoles and is the digital counterpart to the PM100A analog power meter console. The console (and sensor, sold separately) is ideal for use as a CW and pulsed source power meter, incoherent optical source power meter, general light power meter, fiber power meter, and more. The display on the PM100D features adjustable brightness settings, with the option to turn off the backlight completely while still being readable.
The PM100D is compatible with more than 25
This power and energy meter console is also available as a kit, bundled with our most popular sensors. Please visit our power meter kits page for more information. If you have any questions regarding these kits, or would like to suggest other kit options, please contact Tech Support with inquiries.
For a touchscreen version of the PM100D with more advanced spectral correction features, inputs for temperature and humidity sensors, data logging, and additional memory, we offer the PM400 capacitive touchscreen power and energy meter console. We also offer wireless, handheld, self-contained power meters, which feature an ultra-slim sensor with a built-in OLED display as well as Bluetooth® and USB features.
Console Design
The compact housing has a large, 4” backlit display with a resolution of 320 x 240 pixels and illuminated buttons, all of which make operation in dark labs easy. The LCD’s clear GUI offers easy data readouts with an intuitive navigation scheme. Interactive tooltips help to operate the device by giving the user step-by-step operating instructions, displaying the next step on the screen.
The PM100D features four standard measurement screens. The first option is a numeric readout useful for standard power and energy readings. The second option is a tuning needle typically seen on analog devices, however, optimized to run as a digital readout on the display screen. Third is a tuning graph, which is very convenient for fine tuning CW and pulsed sources.
The unit can also be run in a data acquisition mode. Simply start the scan and the unit automatically starts recording data such as current power/energy, minimum, maximum, standard deviation, and other important statistics recorded over the acquisition period. The PM100D also features several user customizable displays and audio tuning for use when the detector is not within visual range. See the Display Screens tab for further information.

Thorlabs' C-Series Power Meter Sensor Connectors Include the Sensor Calibration Data
Connectivity
The sensor connector, shown to the left, enables "hot swappable" quick sensor exchange. The sensor connectors contain all the sensor information including NIST-traceable responsivity curves, sensor types, and model number.
A slot for an SD memory card (an 8 GB SD card is pre-installed) allows data recording even in stand-alone operation, giving the user large memory storage when recording data in the field or away from a computer in the lab. Data can also be recorded via the USB PC connection and optical power monitor software. This software is capable of handling up to eight consoles simultaneously. The features of the PC control software are highlighted in the Software tab.
In addition to remote control operation and data logging/recording, the USB connection can also act as the charging system for the Li-Polymer battery. Also included is an AC battery charger which uses an intelligent charging management system to improve battery lifetime and reduce battery memory effects.
Recalibration Service
Recalibration services are available for our thermal and photodiode power sensors, pyroelectric energy sensors, and consoles. We recommend your Thorlabs sensor and console be recalibrated as a pair; however, each may be recalibrated individually.

Standard Photodiode Sensor Mounting Options
Thorlabs Standard Photosdiode Sensors compact design allows easy integration into existing setups. Typical mounting configurations including post, cage, and lens tube options are available. Shown on this page are several different choices for mounting these sensors.
The Standard Photodiode Sensors are compatible with all S120-xx Series fiber adapters. FC/PC and SMA adapters are shown on the right. Adapters for FC/APC, SC, LC, and ST connections are also available.
Flip up mounts are convenient for quick power measurments from a static location. The sensor can be placed in the path of the laser beam for the power measurment and flipped down during normal operation of the system.
FM90 Right Angle Flip-Mounts are shown to the right. Thorlabs also offers the TRB1 Articulating Post Mount. The lockable articulating mount offers almost unlimited positioning of the sensor head. The articulating mount is shown on an S13xC Slim Photodiode Sensor below.
The Standard Photodiode Sensors also feature SM1 threaded connections on the front face. The SM1 theading provides easy mounting to 1" lens tube systems and quick release mounts.
Shown to the right are the KB1P Quick-Release Post Mount and QRC1A Quick-Release 30 mm Cage Mount. Both mounts feature SM1 threaded connections to the sensor heads.
Note: Due to the thickness of the S12xC sensor, the QRC1A and CP44F (shown below) quick release mounts can only be fully removed from the cage system by backing them off an open end. The two mounts are easily removed from the cage system if only three cage mounts are used. See the picture on the right.
Thorlabs also offers the CP44F 30 mm Cage Plates with Quick-Release Mounts. These mounts feature magnetically coupled mounting for easy and repeatable mounting.
Note: Like the QRC1A, the CP44F can not be removed from a closed cage system.
Slim Photodiode Sensor Mounting Options
Thorlabs' Slim Photodiode Sensors are designed to fit into tight optic arrangements such as cages, lens tubs, and optic dense free space arrangements.
Shown to the right is a S130C Sensor inserted into a 30 mm cage system. The application shown highlights the ease for which the sensor can be inserted into the cage, and the minimal space needed to take a power measurment.
The Slim Photodiode Sensors may also be mounted on a TRB1 Articulating Mount. This mount allows repeatable insertion of the sensor into tight optic arrangements. After the measurement is made, the sensor may be rotated out of the beam path for normal operation.
Microscope Slide Photodiode Sensor Mounting Options
S170C Mounted on a Post
The S170C may be post mounted via the 8-32 (M4) tap in the side of the housing.
The S170C microscope slide power Sensor is designed so that it can be mounted directly in a microscope slide holder. The 76.0 mm x 25.2 x 5.0 mm sensor head has the same footprint as a standard microscope slide and is compatible with most standard upright and inverted microscopes. The photo to the right shows the power sensor flipped over so that the engraved back of the housing can be used for alignment.
This power sensor also has an 8-32 (M4) tap for post mounting. In the photo to the far right, an RA90 is used with two Ø1/2" posts to mount the sensor head in a horizontal orientation.
Integrating Sphere Photodiode Sensor Mounting Options
Thorlabs' Integrating Sphere Photodiode Sensor provides a low loss cavity for diverging, non-uniform, or off-axis beam measurements. These integrating spheres are ideal for all fiber based applications due to the beam divergence at the end of the fiber.
Shown to the right is an S140C Integrating Sphere with S120-FC Fiber Adapter. Also shown is an S140C with a S140-BFA Bare Fiber Adapter. The Bare Fiber adapter features a mounting clamp and light shield to decrease interference from ambient light.
Compact Fiber Photodiode Sensor Mounting Options
Thorlabs' Compact Fiber Photodiodes are the ideal choice for a portable, fiber coupled power meter. The S15xC sensors are compatible with a wide variety of fiber connections. PM20-xx adapters are available to couple FC, APC, SMA, ST, SC, and LC connectors with the sensors. Shown to the right is a S150C Sensor with FC and SMA connector adapters.
Shown to the far right is a PM100D console with S150C sensor connected to a FC connectorized optical fiber. This setup is ideal for portable in the lab and in the field use.
Pyroelectric Energy Sensor Mounting Options
Thorlabs' Pyroelectric Energy Sensors are ideal for measuring pulsed sources. These pyroelectric sensors provide direct energy readings for those sources. The sensors are designed to handle medium to high energy pulses from Excimer, YAG, and other high power lasers.
Mounting options include post (with insulating adapter) and cage configurations, shown to the right.

This tab outlines the full selection of Thorlabs' power and energy sensors. Refer to the lower right table for power meter console and interface compatibility information.
In addition to the power and energy sensors listed below, Thorlabs also offers all-in-one, wireless, handheld power meters and compact USB power meter interfaces that contain either a photodiode or a thermal sensor, as well as power meter bundles that include a console, sensor head, and post mounting accessories.
Thorlabs offers four types of sensors:
- Photodiode Sensors: These sensors are designed for power measurements of monochromatic or near-monochromatic sources, as they have a wavelength dependent responsivity. These sensors deliver a current that depends on the input optical power and the wavelength. The current is fed into a transimpedance amplifier, which outputs a voltage proportional to the input current.
- Thermal Sensors: Constructed from material with a relatively flat response function across a wide range of wavelengths, these thermopile sensors are suitable for power measurements of broadband sources such as LEDs and SLDs. Thermal sensors deliver a voltage proportional to the input optical power.
- Thermal Position & Power Sensors: These sensors incorporate four thermopiles arranged as quadrants of a square. By comparing the voltage output from each quadrant, the unit calculates the beam's position.
- Pyroelectric Energy Sensors: Our pyroelectric sensors produce an output voltage through the pyroelectric effect and are suitable for measuring pulsed sources, with a repetition rate limited by the time constant of the detector. These sensors will output a peak voltage proportional to the incident pulse energy.

(posted 2020-12-14 06:34:06.0) Thank you for your feedback. Please check that you have the latest firmware installed on the PM100D. We have made a few changes regarding the SD card. You can find the firmware download at the link below:
https://www.thorlabs.de/software_pages/ViewSoftwarePage.cfm?Code=OPM user
(posted 2020-11-18 12:44:15.56) Is there a way to reset all settings/memory to the factory default? MKiess
(posted 2020-11-19 09:58:02.0) Thank you very much for your inquiry. Depending on the sensor used, the PM100D can be reset to the default settings for the respective sensors (thermopile, photodiodes, pyroelectric). This can be done under 'System Menu \ Measurement Settings' for the corresponding sensor. Alexander Kuznetsov
(posted 2020-06-30 10:25:33.08) I have a question about the drivers TLPM_32 and PM100D_32.
In our lab, we have a custom software to communicate with several PM100D remotely (e.g. the PM100D is connected to one PC and a user communicates with it from another PC). Such remote communication using PM100D_32.dll via NI-Visa Server works fine. However, devices configured to use the TLPM_32.dll driver are not "visible". Switching the driver to PM100D_32.dll solves it. However I would like to know, how would one achieve the remote communication with the device using TLPM_32.dll?
Thank you in advance. dpossin
(posted 2020-07-03 03:53:47.0) Dear Alexander,
Thank you for your feedback. We switched our software from the NI-VISA based driver PM100D.dll to the more robust driver architecture TLPM.dll. However if you need the old driver for your application we provide a tool called power meter driver switcher is installed together with the power meter software. Please find instructions how to change between the drivers in section 7 here: https://www.thorlabs.com/software/MUC/OPM/v2.2/TL_OPM_V2.2_web-secured.pdf. Also the commands are different compared to the old NI-VISA based driver. Instructions on programming the TLPM driver can be found here: C:\Program Files (x86)\IVI Foundation\VISA\WinNT\TLPM\Manual. I am reaching out to you in order to provide further support. BINBIN ZHAO

(posted 2020-01-09 15:12:26.583) I am using PM100D. Recently, I want to update the firmware. And I connect the PM100D to computer by the monitor software. When I use the software to update the firmware there is always a warning that "user abort the download operation" but I do nothing. Hope for your answer. Thanks. Regards, Yangyang Liu. nreusch
(posted 2020-01-10 08:52:49.0) This is a response from Nicola at Thorlabs. Thank you for contacting us. Could you please check whether you enabled the firmware download mode on the PM100D console (System Menu -->

(posted 2019-12-12 09:13:59.773) I would like to know about "analog output" of PM100D.
Q1, Is the output voltage from analog output "DC" voltage? (Is its wave shape flat?)
Q2, Is the output voltage basically go from 0V to +2.0V? (In a Manual, from -0.3V to +2.3V) wskopalik
(posted 2019-12-12 11:13:29.0) This is a response from Wolfgang at Thorlabs. Thank you for your inquiry!
The voltage signal at the analog output is the amplified photo-diode current or the amplified thermal or pyroelectric sensor voltage. So the voltage will change corresponding to the power of the incident light. If the incident light is CW, the signal will be a flat voltage signal. If the incident light is however modulated or pulsed, the signal will be modulated or pulsed as well.
The range of 0V to 2V is the range in which you will get reliable measurement results. If e.g. the amplifier or the sensor are saturated, it is however possible that you get voltages in the range of -0.3V up to +2.3V. So the devices attached to the analog output should be able to handle voltages in this range without any damage.
I will contact you directly to provide further assistance. A. Devine
(posted 2019-12-02 15:49:34.81) While polling a thermopile sensor over USB with the PM100D (using the LabVIEW drivers), occasionally NaN is returned instead of an actual power reading value. This seems to happen most frequently when readings are taken too close together. I have solved the problem by adding a 20 second delay between readings, but this seems too large. I do not experience the same behavior with the PM200 or newer power meters. I would appreciate any insight as to why the meter is returning NaN so that I can work on a more elegant solution.
Thanks,
AD MKiess
(posted 2019-12-05 09:32:58.0) This is an response from Michael of Thorlabs. Thank you very much for your inquiry. I have contacted you directly to discuss the specifications and measurement procedure of your light source, as well as the programming to find a solution together. Ian Roberts
(posted 2019-10-29 19:32:01.613) Using the SCPI commands in the manual I can communicate with the PM100D over USB to read the instantaneous power, which works well. However, I want to record data at a high rate (ideally every millisecond) which is too fast for serially polling the device using the MEAS power command.
As the device can make measurements very rapidly and store the data to a CSV file, is it possible to read this data / transfer the file (once measurement is finished) over USB using SCPI commands? Or some other way (e.g. mounting the storage as a device the computer can access?)
I appreciate Thorlabs offer a driver package / GUI but having to install separate software is highly unattractive (/ not even possible in some situations due to lack of admin rights). Thanks. MKiess
(posted 2019-10-31 08:55:39.0) This is a response from Michael at Thorlabs. Thank you very much for the inquiry. The limitation here is due to the data transfer rate of USB. However, you can use the analog output, which has a bandwidth of up to 100kHz. I contacted you directly to find a suitable solution for your application together. DAVID KINGHORN
(posted 2019-06-07 20:44:24.12) What is the part number for the AC Battery Charger for the PM100D Console? MKiess

The function principle for these sensors is different compared to Thermopiles or Photodiodes. Pyroelectric sensors (ES-Series) do only generate a signal when an optical pulse is detected.
The pulse energy needs to be larger than the threshold which is defined via trigger level thus when setting trigger level to very low values you can observe noise. The measurement value will be updated with each incoming pulse and when no pulses appear the measurement display will be held on the last measured value.

I am currently working with a spectrometer and the optical powermeter PM100A from thorlabs. My question to you guys is how the powermeter calculates the optical power from W into W/cm². Which area is chosen therefore? Another question is how the optical power is calculated itself. Is that done by a sort of integration over a range of wavelengths around the 'preferred wavelength' in the settings?
This is very important for me since the data from a spectroscope are not corresponding to data from the PM100A.

PM100A can not display power densities so I think this is about PM100D. To display the power density in W/cm² in the right sub display it is necessary to enter the diameter of the incident beam or at an overfilled sensor the diameter of the sensor aperture. In the Meas Config menu the beam diameter can be set. I have contacted you directly for further assistance. lokirune

We are using PM100D to measure optical power of LEDs. The wavelength of LED is 850 nm. The sensor that we used is S120C which can measure from 400nm-1100nm. We set 850 nm at PM100D and get measurement. We also tried to set various wavelengths (400, 500,.., 1000, 1100 nm and so on) and get measurements. It is observed that the peak power is occurred to be at 1100 nm and the power at 850nm is lower than most of the measurement powers at other wavelengths. Please kindly advise. Appreciate if you could contact us. Thanks. wskopalik
(posted 2017-10-05 04:54:48.0) This is a response from Wolfgang at Thorlabs. Thank you very much for your inquiry.
The wavelength you enter on the PM100D determines which responsivity is used to convert the current coming from the photodiode into a power values. This is necessary due to the spectral dependence of the responsivity of photodiodes. The sensor itself can however only measure the total power of a beam and cannot separate different wavelengths. This can lead to inaccuracies when you measure LEDs with a wide spectral distribution, because some parts of the spectrum may not be converted with the correct responsivity.
The difference in the results you see is basically the spectral dependence of the responsivity of the sensor. The responsivity is quite low around 400nm and 1100nm, in between it increases to a maximum at around 950nm - 1000nm. You should see the inverse of that in the power values when you change the wavelength which agrees with what you have seen.
I have contacted you directly to discuss all this in more detail. DingR.F.1987

(posted 2016-03-07 09:21:29.703) I'm using your device for the real time monitoring of few msec wide optical pulses, therefore I have the same problem as described in the previous message by gbeckford93.
By writing my own application which only requests the data, I have done precise timing tests on your device and found that it is possible to increase the number of samples per second by concatenating multiple "READ?" on the same SCPI command.
As example, by issuing the SCPI command "READ?;READ?;READ?;READ?;READ?" the instrument will respond with a string containing a list of 5 measurement that, if the averaging is set at 1 and auto range is disabled, are separated by 2.338 msec (2.369 msec with auto range enabled) instead of the 3 msec separation that would be obtained by retrieving the measurements by means of consecutive "READ?" in separate SCPI commands.
Unfortunately, the FIFO buffer dedicated to the device output is only 256 bytes and the buffer filling condition is not handled by the firmware so, if the SCPI responce string requires more than 256 bytes, all the exceeding chars will be lost.
Considering then that each measurement is transfered to PC using 15/16 ASCII chars (depending on sign), only up to 16 measurement can be requested on a single SCPI command without the risk of receiving an ASCII string truncated to 256 chars.
By retrieving then arrays of 16 measurements, rather than single values, my application is able to read from your device up to 416 samples per second that (a part a small gaps between the arrays) are equispaced by 2.338 msec
Considering that time requested for ADC conversion is only 0.333 msec, the remaining 2 msec are entirely spent by the device firmware to process the data and could certainly be significantly reduced if two additional SCPI Commands, rather standard in this kind of instruments, were implemented also in your device:
- "CONFigure:ARRay" and "READ:ARRay?"
to setup and retrieve an array of multiple
measurement in a single com shallwig

(posted 2016-01-28 06:39:37.0) This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. The sampling speed of the currently available software is limited to around 300 Hz. This limitation has several reasons, mainly from the GUI which queries also the status of the device and sensor and saves the data into a file.This could be bypassed by writing a short own application which only requests the data. In the Software package also drivers for Labview, Visual Basic, C++ and C# are included.
You can download Power meter application notes for programming from the “Programming Reference” Tab http://www.thorlabs.com/software_pages/viewsoftwarepage.cfm?code=PM100x&viewtab=5
Another limitation for getting equidistant data will be the USB connection. Sampling at 1 kHz is possible by using the PM100Ds Analog output. The Bandwidth is DC-100 kHz dependent on the sensor.

thanks! shallwig
(posted 2015-05-27 06:48:28.0) This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. All our detectors are only NIST traceable calibrated in terms of absolute power. The setup we use for calibrating our sensors can be found on our website in the power meter tutorial if you click on the “calibration” Tab: http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=6188
We use a monochromator which has about 2mm beam diameter. Therefore the aperture dimensions and its tolerances are uncritical for the S120VC and S120C. Both have an input aperture of 9.5mm diameter.
First a reference scan is carried out and the reference current (IRef) vs. wavelength is recorded. This allows the calculation of the optical power at each wavelength step. The Reference photodiodes are recalibrated annually at PTB or NIST, which gives the traceability. After that we replace the reference by the diode under test (DuT) and repeat the wavelength scan. This time the current (IDuT) vs. wavelength gets recorded.
During any calibration scan, a monitor diode is used to observe power variations due to lamp aging. The ratio of the actual monitored value during calibration to that during the reference scan is used to correct the calibration scan. As soon as the deviation exceeds 1%, a repeated reference scan is carried out. The responsivity of the DuT is then calculated over the entire specified wavelength range of the DuT with a step size of 5 nm. These data sets (responsivity and wavelength) are saved to the sensor's memory, located in the DSUB connector. Additionally, the calibration data are printed out to the Certificate of Calibration and are saved to our server.
Irradiance you can also display with our power meter consoles by entering the beam diameter. But the given value is a calculation made from the measured optical power and the beams dimensions.
I will contact you directly to discuss your needs in more detail. lhkorea

Furthermore, these shows radical power data change when 'Range' is changing to upper or lower range at 'Auto range on' state (for example, if power data is 44uW within ~45uW range, after then, the power data increases slightly over 45uW, the power data is just changed to around 130uW right after the measurement range is changed to ~450uW.) This problem applies to all PM100Ds and S155Cs we have. I think there is some problem about sensing calibration between pm100D and S155C(power measurement using a S146C sensor head has no problem now). At the first time when we used these devices, there was no problem like this. I don't know the reason of this problem exactly, but I guess this problem was caused since we used these devices by connecting to PC. Power measurement using PC software fixes the range option as 'Auto range', so we can't avoid this problem. Please reply asap. Thanks. shallwig

The analog output provides the amplified photodiode current or the amplified thermal or pyroelectric sensor voltage.
With thermal sensors the analog output shows the direct amplified and accelerated voltage response from the sensor. With pyroelectric sensors the signal from the analog output is the pulse response from the sensor prior to the peak detection circuit.
The signals from the analog outputs are not wavelength and zero corrected.
The analog output voltage is range dependent and can be calculated to:
U(out)[V] = 2V / full scale range value [V,A] x measurement value [V,A]
The analog output voltage can go from -0.3V to +2.3V. abul_ukproject

(posted 2013-07-22 11:27:00.0) a response from Julien at Thorlabs: thank you for your feedback! the S120C only contain a resistive sensor to ensure that they are not overheating but cannot log the temperature directly. we offer a small USB temeprature logger (TSP01) that can be used in conjuncction with the power meter lines to log the temperature of the sensor over time. The requirement for such an external temperature logge rin this type of application is of course related to the incoming optical power. I will contact you directly to see which optin is the msot suited to your requirements. pt_tanyingjie
(posted 2013-06-19 04:37:51.34) I need to insert some labview source codes of PM100A/D into another measurement labview program. In the program, I need the power meter to set the wavelength of a monochromatic light, then measure the light intensity, meanwhile, save the wavelength value, light intensity into a file. Then, go to the next wavelength monochromatic light, then PM100 set this wavelength, measure the intensity,and so on.
The problem I encountered is, the labview source codes in the USB in the package(or from the Thorlabs webpage)cannot work. PM100 has no response to these labview source codes.(e.g. set wavelength). And many of them are bad subVIs.(e.g.PM100-PM200 Utility).
So could you help me with it?
Thank you very much again! tschalk
(posted 2013-06-20 09:22:00.0) This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. The software which can be downloaded from our homepage (https://www.thorlabs.com/software_pages/ViewSoftwarePage.cfm?Code=PM100x) contains the sub VIs necessary to access all of the functions which you require for your software. The LabVIEW Library is located in the folder: C://Program Files/National Instruments/LabVIEW X(latest version on your pc)/instr.lib/PM100D. You can access the individual functions through the function panel of LabVIEW: Instrument I/O -> Instrument Drivers -> PM100D. Two important functions to get a response from the power meter are the PM100D Initialize.vi and the PM100D Close.vi. The device must be initialized before you can use the other functions to control the power meter. At the end of the program the device must be closed. If you don't use the initialization and closing there will be problems with getting any response from the device. I will contact you directly for more detailed information. user
(posted 2013-06-18 06:22:41.263) We have a PM100D and a S150C sensor. The sensor is specified to have a resolution of 10pW, yet the numeric view does not display any digits below 0.1nW. The statistics view and the PC utility have enough digits to display 10pW and below, so the information must be there. Is there any way to make the numeric view display more digits with the S150C? tschalk
(posted 2013-06-19 11:50:00.0) This is a response from Thomas at Thorlabs. The display of the PM100D has 4 digits which is unfortunately not configurable. The highest resolution is then 100pW. If you want to archive higher resolution you can use the statistics screen or a connection to the computer. When using the console remotely, you are able to achieve a resolution of 1pW. tttang

Can not I use the USB interface to the PC (~1kHz sample rate)? jvigroux
(posted 2013-03-04 08:41:00.0) A response from Julien at Thorlabs: you could use the USB logging software but please keep in mind that the sample rate is not fixed and will depend on your computer also. This means that you could possibly, based on your setup have a sample rate (when using the logging software) of a few 100Hz. This in turns means that you would have only a few point per laser cycle, which could potentially be a problem. jvigroux
(posted 2013-02-28 07:52:00.0) a response from Julien at Thorlabs: Thank you for your inquiry. The display of the PM100D has a refresh rate of 20Hz so that you will not be able to follow your 100Hz directly on the display. When setting the bandwidth to "high", you should however be able to see your signal both when using the logging program (~1kHz sample rate) or the analog output (100kHz bandwidth maximum). for modulation frequency at 1kHz, the only option is to use the analog output. jvigroux

(posted 2012-06-17 22:25:59.0) Hi,
We bought a PM100D with a S130C sensor last month. We are trying to quantify the power output (mW) of a blue DPSS laser sending 5 ms pulses using the PM100 utilities software. We are unable to achieve sufficient sampling rate with this software, even when setting averaging to minimum (i.e. 1) and interval between samples to zero. In that case, we obtain about 35 samples/sec (and a noisy signal). We would like to achieve a better sampling rate using this software (i.e. 3Ksamples/sec). Any suggestions ? Thanks ! tcohen
(posted 2012-05-25 09:47:00.0) Response from Tim at Thorlabs: Thank you for using our feedback tool! This happens if the console is in “Relative Measurement” operation mode. In this mode, the left and right sub-menus are fixed and used for “Ref” power and “P” current power, while the main display shows the difference with a + or – sign. If you push the delta “?” button to return to normal measurement mode, the sub menus will again be programmable. user

(posted 2009-03-06 14:42:51.0) We just bought the old style meter (~2 months ago) along with a slim cell sensor and thermal sensor.
It appears now that we cannot get a second meter of the style that would fit our current sensor cells. Is that correct?
What would the cost be to change the connectors to the current style on our 2 sensor? We are interested in having two meter and sensors that are interchangeable. It looks like your product revisions have prevented us from achieving this.
What are our options? |
Thorlabs offers a wide selection of power and energy meter consoles and interfaces for operating our power and energy sensors. Key specifications of all of our power meter consoles and interfaces are presented below to help you decide which device is best for your application. We also offer self-contained wireless power meters and compact USB power meters.
When used with our C-series sensors, Thorlabs' power meter consoles and interfaces recognize the type of connected sensor and measure the current or voltage as appropriate. Our C-series sensors have responsivity calibration data stored in their connectors. The console will read out the responsivity value for the user-entered wavelength and calculate a power or energy reading.
- Photodiode sensors deliver a current that depends on the input optical power and the wavelength. The current is fed into a transimpedance amplifier, which outputs a voltage proportional to the input current. The photodiode's responsivity is wavelength dependent, so the correct wavelength must be entered into the console for an accurate power reading. The console reads out the responsivity for this wavelength from the connected sensor and calculates the optical power from the measured photocurrent.
- Thermal sensors deliver a voltage proportional to the input optical power. Based on the measured sensor output voltage and the sensor's responsivity, the console will calculate the incident optical power.
- Energy sensors are based on the pyroelectric effect. They deliver a voltage peak proportional to the pulse energy. If an energy sensor is recognized, the console will use a peak voltage detector and the pulse energy will be calculated from the sensor's responsivity.
The consoles and interfaces are also capable of providing a readout of the current or voltage delivered by the sensor. Select models also feature an analog output.

The 5 mm thin sensor end can fit between closely spaced optics, cage systems, and other arrangements where standard power meters may not fit. The NIST-Traceable, calibrated sensors also feature a large Ø9.5 mm sensor aperture and slideable neutral density filter for dual power ranges in one compact device.
A separately available SM1A29 adapter can be attached by 2 setscrews to any S130 series power sensor to mount fiber adapters, light shields, filters or any other SM1-threaded (1.035"-40) mechanics or optics. The FBSM Mount allows our S130 series power sensors to be mounted vertically into FiberBench systems for stable mounting with a minimal footprint.
Thorlabs offers a recalibration service for these photodiode power sensors, which can be ordered below (see Item # CAL-S130 for Si sensors and Item # CAL-S132 for Ge sensors).

The S170C Microscope Slide Power Sensor Head is a silicon photodiode sensor designed to measure the power at the sample in microscopy setups. The silicon photodiode can detect wavelengths between 350 nm and 1100 nm at optical powers between 10 nW and 150 mW. The sensor head's 76.0 mm x 25.2 mm footprint matches that of a standard microscope slide and is compatible with most standard upright and inverted microscopes.
The photodiode has an 18 mm x 18 mm active area and is contained in a sealed housing behind a neutral density (ND) filter with OD 1.5. A 20 mm x 20 mm indentation around the surface of the ND filter is sized to accept standard microscope cover slips. An immersion medium (water, glycerol, oil) may be placed in this well directly over the ND filter, or a cover slip may be inserted first to simplify clean up. The gap between the photodiode and the neutral density filter has been filled with an index matching gel in order to prevent internal reflections from causing significant measurement errors when using high NA objectives with oil or water.
The bottom of the sensor housing features a laser-engraved grid to aid in aligning and focusing the beam. In standard microscopes, this grid can be used for beam alignment before flipping the sensor head to face the objective for power measurements. In inverted microscopes, turn on the transmitted illuminator to align the grid on the detector housing with the beam, thereby centering the sensor in front of the objective. Alternatively, the diffusive surface of the ND filter can be used as a focusing plane.
Sensor specifications and the NIST- and PTB-traceable calibration data are stored in non-volatile memory in the sensor connector and can be read out by the latest generation of Thorlabs power meters. We recommend yearly recalibration to ensure accuracy and performance. Calibration may be ordered using the CAL1 recalibration service available below. Please contact technical support for more information.

These Integrating Sphere Photodiode Power Sensors are the ideal choice for power measurements independent of beam uniformity, divergence angle, beam shape, or entrance angle, making them excellent for use with fiber sources and off-axis free space sources.
Our integrating spheres are designed for wavelength ranges from the visible through the NIR. Sensor heads for use between 350 and 2500 nm use a single Ø1" or Ø2" sphere made from Zenith® PTFE and feature a black housing to minimize reflected light around the entrance aperture. These sensors use either a silicon photodiode for detection in the 350 - 1100 nm range or an InGaAs photodiode for detection in the 800 - 1700 nm, 900 - 1650 nm, or 1200 - 2500 nm wavelength range.
The S180C integrating sphere for 2.9 - 5.5 µm uses two connected, gold-plated Ø20 mm spheres, with an entrance port in the first sphere and a port for the MCT (HgCdTe) detector located in the second sphere. Compared to single-sphere designs, the two-sphere configuration improves device sensitivity by minimizing the internal sphere surface area while still effectively shielding the detector from direct illumination. This design reduces the effect of input angle, divergence, and beam shape on the measurement result by effectively shielding the photodiode without the use of a baffle or other shielding mechanism.
The integrating spheres below feature large Ø5 mm, Ø7 mm, or Ø12 mm apertures, externally SM1-threaded (1.035"-40) front connections, enhanced shielding against electromagnetic interference, and an over-temperature alert sensor. Because of the large active detector areas of these sensors, the included S120-FC fiber adapter can be used with FC/PC- or FC/APC-terminated fiber. The externally SM1-threaded adapter can be removed using a size 1 screwdriver to place components closer to the window. NIST-traceable data is stored in the sensor connector.
Thorlabs offers a recalibration service for these photodiode power sensors, which can be ordered below. See Item # CAL1 for the S140C and S142C Si sensors; Item # CAL2 for the S144C, S145C, and S146C InGaAs sensors; and Item # CAL4 for the S148C InGaAs sensor or S180C MCT sensor.

S401C Thermal Sensor with Included Light Shield
Thorlabs offers two broadband thermal power sensors designed to measure low optical power sources with high resolution. Each thermal sensor's broadband coating has a flat spectral response over a wide wavelength range, as shown in the plot below.
An aperture size of Ø10 mm allows for easy alignment and measurement of large-spot-size laser sources. For easy integration with Thorlabs' lens tube systems and SM1-threaded (1.035"-40) fiber adapters, each sensor has either external SM1 threading or includes an externally SM1-threaded adapter.
The S401C uses active thermal background compensation to provide low-drift power measurements. This is implemented through the use of two similar sensor circuits. One sensor circuit is the type all thermal power sensors share: it measures heat flow from light absorber to heat sink. The other sensor circuit monitors the ambient temperature. It is located within the housing and measures heat flow from heat sink towards the absorber. The measurements of the two sensor circuits are subtracted, which minimizes the effect of thermal drift on the laser power measurement. (For information about how the external thermal disturbances can affect thermal power sensor readings, see the Operation tab.) The broadband coating used on this thermal sensor offers high absorption at wavelengths between 0.19 and 20 µm (shown in the graph), which makes the sensor ideal for use with aligning and measuring Mid-IR Quantum Cascade Lasers (QCLs). The included, internally SM05-threaded (0.535"-40) light shield is shown in the photo to the right.
The S405C has internal SM05 (0.535"-40) threading that is directly compatible with SM05 lens tubes, and it can also connect directly to Thorlabs' 30 mm Cage Systems.
Thorlabs offers a recalibration service for these sensors, which can be ordered below (see Item # CAL-S200).

These thermal power sensors are designed for general broadband power measurements of low and medium power light sources. All include an externally SM1-threaded (1.035"-40) adapter, with threading concentric with the input aperture. The adapters are useful for mounting Ø1" Lens Tubes and Fiber Adapters (available below). The apertures of the S415C and S425C have internal SM1 threading.
These sensors operate with fast (<0.6 s) natural response times, and their removable heat sinks provide a high degree of flexibility to those interested in integrating them into custom setups or replacing the included heat sink with one that is water or fan cooled. If replacing the heat sink, please note that the replacement must provide heat dissipation adequate for the application.
Thorlabs offers a recalibration service for these sensors, which can be ordered below (see Item # CAL-S200).

- Designed for Optical Power Measurements of Nd:YAG Lasers
- Ideal for Applications with High Peak Pulse Powers
- S370C: Ø25 mm Aperture for Large-Spot-Size Beams
- S470C: High-Sensitivity for High-Peak-Power Pulses with Low Average Power
- See the Full Web Presentation for More Information
The S370C and S470C Thermal Sensors are designed to measure short and highly energetic laser pulses. All of these units are post-mountable for free-space applications and feature NIST-traceable data stored in the sensor connector.
These thermal power sensors are unique in that they have thermal volume absorbers, where our other thermal power sensors have thermal surface absorbers. The volume absorber consists of a Schott glass filter. Incident pulses are absorbed and the heat is distributed throughout the volume. In this way, pulses that would have damaged the absorption coating of a thermal surface absorber are safely measured by these thermal volume absorbers.
The S370C features a large Ø25 mm aperture ideal for large-spot-size beams, and it is compatible with average powers from 10 mW to 10 W (CW).
In comparison, the S470C is faster, as the glass absorber volume is reduced and other design parameters have been optimized for speed. This results in a different optical power range, with the ability to measure powers down to 100 µW. The Ø15 mm aperture is of the S470C is smaller, and it has a lower max average power of 5 W. Its 10 µW resolution is better than the 250 µW resolution of the S370C.
Thorlabs offers a recalibration service for these sensors, which can be ordered below (see Item # CAL-S200).

These Pyroelectric Sensors are designed to measure pulsed coherent and incoherent sources. Pyroelectric sensors are not suited for CW measurements, as they convert energy from light pulses into voltage pulses. A black broadband or ceramic coating is used for low or high power measurements, respectively. Large sensor areas from
Ø11 mm - Ø45 mm allow easy alignment. The energy sensors features BNC connectors for use with an oscilloscope, as well as standard power meter connectors which contain NIST and PTB-traceable calibration data.
These sensors are not compatible with the PM100A Analog Power Meter Console or the PM101 Series Power Meter Interfaces.
Thorlabs offers a recalibration service for these energy sensors, which can be ordered below (see Item # CAL-S200).
