Thorlabs' PT Translation Stages have a 1.00" (25.0 mm) translation range and feature hardened steel linear bearings for precise motion and long life. These translation stages are available preconfigured with an adjuster screw, standard manual micrometer, or differential adjuster. The actuator on the translation stage can be removed by loosening the screw on the barrel clamp with a 3/32" (2.5 mm) hex key.
Each stage comes with two precision dowel pins that allow the PT series of translation stages to be stacked in right- or left-handed XY configurations with excellent orthogonality of <5 mrad. The right-handed XYZ configuration, with either the standard manual micrometer or the differential micrometer, is available fully assembled below.
Custom Options
Any PT series translation stage can be purchased as a special order without a micrometer, thereby allowing the user to choose from our large selection of manual and motorized actuators. We also offer screw adjusters that have Ø3/8" barrel adapters for 1/4"-80, 1/4"-100, or M6 x 0.25 threads, making them compatible with the stages below. Please see the selection guide in the Actuators tab for a list of compatible actuators. Please contact Tech Support to discuss the various micrometer options and to get quotes for custom configurations with or without alternative actuator options.
PT101(/M) Base Plate
The PT101(/M) Base Plate is ideal for XY or XYZ multi-axis configurations where the standard counterbores in the middle of the stages are obstructed. It has 1/4" (M6) counterbore slots for mounting to a breadboard or optical table and comes with the two 1/4"-20 (M6) cap screws that are needed to attach it to a PT series stage.
PT102(/M) Angle Bracket
The PT102(/M) Angle Bracket allows for a PT series stage to be oriented vertically, making left- or right-handed XYZ, XZ, and XY configurations possible. For information on constructing an XYZ configuration from individual components, see the XYZ Assembly tab.

XYZ Assembly
The modular design of the PT series translation stages allows the assembly of 2- or 3-axis stages within minutes. Each stage comes with two precision dowel pins that allow for right- or left-handed XY configurations with excellent orthogonality. Follow the steps in the animation to the left or the photos below to build a 3-axis XYZ translator (PT3) from individual components.
Step One
Insert the two 1/8" alignment pins into the PT101(/M) Base and then screw it onto a PT series translation stage using the two included 1/4"-20 (M6) cap screws. Then insert the two 1/8" alignment pins into the provided holes to ensure orthogonality of the second stage.
Step Two
Attach the second, orthogonal PT series translation stage, as shown above, using two 1/4"-20 (M6) cap screws. Then insert the two 1/8" alignment pins into the provided holes for aligning the angle bracket.
Step Three
Screw the PT102(/M) Angle Bracket to the PT series translation stage, as shown above, using two 1/4"-20 (M6) cap screws. Then insert the two 1/8" alignment pins into the provided holes on the front face of the angle brakcet for aligning the third and final stage.
Step Four
Screw the third PT series translation stage to front of the PT102(/M) Angle Bracket, using two 1/4"-20 (M6) cap screws.

Digital micrometers, such as the DM713, are handy for moving a piece of optomech a specific distance. For example, a user might want to increment a translation stage holding a sample in front of an objective lens in order to focus the light to equally spaced points within the sample.
However, there are also times where the user might want to record the position of an event. One example could be making a distance measurement where the micrometer is set to a starting position, zeroed, and then translated the desired amount to display the distance.
Using the DM713 alone creates an extra step where the user has to read and record the display, which can be tedious in a dark lab where the display is not visible. One solution is to use Thorlabs' SBC-COMM, which includes an RS-232 interfacing cable. Thorlabs has created software application notes that walk the user through creating Visual C#® and LabVIEW® programs to continuously measure distances with the DM713. The application notes can be downloaded from links in the following section.
Another solution is to purchase the Mitutoyo® 05CZA662 SPC cable and IT-016U USB input tool that provide a push button and USB interfacing cable. With this device the user can open any text entry software package, press the single push button, and the device acts like a keyboard to enter the number into the software.

(posted 2019-03-12 10:53:27.517) Hi,
Is it possible to get the PT3 with imperial tapped holes, but a metric micrometer.
Thanks,
Tom. llamb
(posted 2019-03-12 03:41:47.0) Yes. You may manually swap the 150-801ME metric micrometers into the PT3 after removing the imperial 150-811ST micrometers. Otherwise, you may contact techsupport@thorlabs.com for requests on custom pre-configured products. We have reached out to you by email to quote this particular custom product. mark_bowen
(posted 2017-12-12 17:03:32.893) We have used hundreds of PT1 stages in the past. They proved to lack sufficient stiffness for my recent application, so I considered the DTS25 as an option. The website provides stiffness specs for the DTS, but the specs for the ball and roller slides do not. That would be a helpful characteristic to list so the products can be compared. tfrisch
(posted 2017-12-15 09:51:06.0) Hello, thank you for contacting Thorlabs. PT1 has its micrometer attached to the moving carriage rather than the baseplate, so likely the effect you are seeing is due to the weight or torque of your hand moving the stage. I will pass on your note about product comparison characteristics to our Engineering Team. clare.dillon
(posted 2016-07-25 09:55:33.307) I wondered if you could tell me what the repeatability of the PT1/M micrometer is please, and what the hysteresis is in the mechanism? Thanks. cpepe
(posted 2016-06-07 15:11:55.133) Hi, I was wondering if you could tell what material the "XYZ Translation Stage with Standard Micrometers PT3/M" is made of? besembeson
(posted 2016-06-08 09:42:26.0) Response from Bweh at Thorlabs USA: It is mostly anodized aluminum (for the main body) and hardened alloy and stainless steel for other sub components. tomerg
(posted 2015-11-04 09:03:15.663) Hello, I want to inquire regarding the PT1A/M: the distance between the CBORE for M6 is 25.4mm while for most of the metric products the mounting holes distance is 25mm. Is it Ok? is there enough freedom to assemble the PT1A/M on metric items (specifically, AP30/M)?
Thanks, Tomer. jlow
(posted 2015-11-04 11:57:47.0) Response from Jeremy at Thorlabs: The counterbored holes on the metric PT1-series stages are oversized so they can be used on 25mm hole pattern. t.isaac
(posted 2015-05-05 10:51:24.09) Please could you tell me the maximum cantilevered load (axial and transverse) of the PT1A/M stage? cdaly
(posted 2015-05-18 08:50:40.0) Response from Chris at Thorlabs: At the moment, we do not have measured limits for the permissible torque on the PT1 series of stages, but we will contact you directly in order to discuss your application and how appropriate this stage if for you. khaded
(posted 2014-12-05 10:31:14.7) How can I order the PT3 stage with the bottom stage rotated 180 deg. (because of interference of the micrometer with another component).
Thanks,
Kevin Haded cdaly
(posted 2014-12-05 05:49:18.0) Response from Chris: To order a left handed version, or any other custom, you can request this from us at techsupport@thorlabs.com. I will contact you directly about this, but it should be noted that the stage can easily be disassembled and reoriented using just a 3/16" hex key. fitilis
(posted 2014-03-27 10:58:29.427) Is there a lock screw on the stage to prevent movement of the stage when the position is set? cdaly
(posted 2014-03-27 04:25:11.0) Response from Chris at Thorlabs: The PT1 series of stages do not have a locking mechanism. The 1/2" travel MT1 and 1" travel LNR25M do have a locking mechanism though. davoodahadpour

(posted 2013-10-03 14:19:41.457) Hello,
I am planning to use a PT1B/M mounted vertically. Do you offer any locking rings for the ¼”-170 adjustment screw of the stage, if not is there another adjustment screw with locking rings compatible with the stage?, an adjustment screw with a coarser pitch will not be a problem for my application. Thank for your time.
TA tcohen
(posted 2013-10-03 12:46:00.0) Response from Tim at Thorlabs: Thank you for contacting us. We do sell locking rings separately for other adjustment screws which could be fitted (http://www.thorlabs.com/navigation.cfm?guide_id=131). For this TPI, although these aren’t in our catalog yet, we can likely offer them as a special. I see you haven’t left us any contact information, so if you would like to discuss this further and receive a quote, please contact us at techsupport@thorlabs.com. tcohen
(posted 2012-10-19 18:18:00.0) Response from Tim at Thorlabs: To avoid obstructing the path during translation underneath the mounting body, the screws should not exceed the length of the tap, which is just over 5.8mm. dnelson
(posted 2012-10-19 12:46:20.46) What's the maximum lnegth of 1/4-20 screws that can be used with the PT1? Buki at Thorlabs
(posted 2011-01-26 14:10:20.0) We have tested the PT1/M in a similar setup by mounting a P4 (4” long post), a PT3 and then two MB12s (6kg total) onto the P4 post. In this arrangement, the vertical stage still moves smoothly so you should not experience any degradation in performance.

i need to mount a PT1/M Translation Stage on a breadboard with 50.0mm hole spacing. What would you recommend since the PT101 has a 51mm hole spacing? Can you use the PT101 also with 50mm hole spacings?
Thank you for your answer. Adam
(posted 2010-03-19 09:19:46.0) A response from Adam at Thorlabs to Bowen: The distance from the bottom of the stage shown in detail A to the table top is 35.67mm when the stage is midway in travel. I will email you directly to see if any more dimensiosn are needed. bowen
(posted 2010-03-19 08:37:47.0) For the drawing of PT3, what users would like to know is the height of detail A above the tabletop (where the stage would rest). This value does not seem to be in the drawing. Youd really like to know it when the micrometer is in the midrange, not at one end of the travel. jens

Thank you for brining our attention to the PT3 image. The picture was not accurate and has been replaced. The block is not part of the PT3 (Please see the updated image). jschumacher
(posted 2007-11-13 05:20:31.0) if I click on PT3 a picture is shown that includes a block between the second and third stage. This block would be very helpful. Which item number is it? acable
(posted 2007-08-20 13:25:06.0) It would also be nice to use the same sort on the price box for the metric products as is used for the imperial products. Also even if the PT101 is truely universal i would list it in both price boxes, it is arkward to need to go into two places to put together a system. europe
(posted 2007-08-20 10:43:38.0) please take a look on the web page for PT101 :
there is no hint for customers that the PT101 is universal ( if so why does it have 1/4-20 tap???) and fits with the /M parts - can you advice with the web team that they do a comment?

Manual Linear Translation Stages
Thorlabs' manual translation stages are offered in a range of maximum travel distances, from less than 1/4" (6 mm) to 2" (50 mm) and longer for our long travel, large area platforms. Many of these stages can be ordered in multi-axis configurations, providing XY or XYZ translation. For fiber coupling applications, please see our Multi-Axis Stages, which offer finer adjustment than our standard manual translation stages. In addition to linear translation stages, we offer rotation stages, pitch and yaw platforms, and goniometers. We also offer motorized translation stages that are powered by DC Servo motors, stepper motors, or direct drive technology.

- Preconfigured, 3-Axis, Right-Handed XYZ Translators
- Fully Assembled Stages Include both the PT101(/M) and PT102(/M) Adapters Plates
The PT3(/M) translation stage is fitted with standard 1" 150-811ST micrometer drives, each of which is engraved every 0.001", while its metric counterpart (PT3/M) comes with 150-801ME micrometers, which offer 25 mm of travel and are engraved every 10 µm. Each stage offers sixteen 1/4"-20 (M6) tapped mounting holes that are 0.22" (5.8 mm) deep.
The PT Series of translation stages can be purchased individually (PT1 Series above) or as fully assembled, 3-axis, XYZ translators (PT3 Series). Therefore, the PT3 stage can be disassembled using a 3/16" (5 mm) hex key to customize the positions of the micrometers or to use three PT1 stages separately, see the XYZ Assembly tab for details.
Please contact technical support if your application would benefit from a stage that is equipped with imperial taps and metric micrometer drives or vice versa.

PT101 Base Plate used to create clearance for mounting a DM713 Digital Micrometer to a PT1 Stage.
- Build XY and XYZ Configured Stages
- Base Plate for Optical Breadboard Mounting
- Angle Bracket for Vertical Mounting
The PT101(/M) and PT102(/M) are adapter plates designed for the PT Series translation stages. The PT101(/M) has four 1/4"-20 (M6) mounting slots on the side that enable obstruction-free mounting onto an optical breadboard. It is ideal for XY configurations or already assembled XYZ multi-axis configurations where the standard counterbores in the middle of the stages are obstructed. This base plate includes two alignment dowel pins and two 1/4"-20 (M6) cap screws.
The PT102(/M) is an angle bracket with four 1/4"-20 (M6) mounting holes that allows a PT Series stage to be mounted vertically. This is necessary in all XZ and XYZ configurations. The adapter plate includes four 1/4"-20 (M6) cap screws. It is also compatible with our manual and motorized MT Series translation stages that offer 1/2" (25 mm) of travel. This allows stages with different travel ranges to be easily connected within the same mechanical system.
The PT3(/M) XYZ configured stages include both the PT101(/M) and PT102(/M) adapters. Please see the XYZ Assembly tab for more information on using these adapters to create a multi-axis configuration.
