These UV LEDs are compact light sources in a hermetically sealed TO-39 package with an integrated ball lens. They provide an output power of at least 1 mW at peak wavelengths from 250 nm to 280 nm, with a small viewing half angle of 7.5°. An exceptionally long lifetime of at least 1000 hours ensures uninterrupted, continuous operation. With these specifications, these UV LEDs are well suited for a wide range of applications including disinfection, forensic analysis, and optical sensing and imaging of biological markers.

These UV LEDs can be mounted in Thorlabs' SM-threaded passive mounts for LEDs, such as the SM1 (1.035"-40) threaded S1LEDM. The LEDs generate up to 1 W of heat and must be kept at a case temperature below 55 °C at a forward current of 100 mA. For temperature regulation, the passive HSLT2 heat sink lens tube is recommended for use with the S1LEDM mount. The TO-39 package of the UV LEDs follows a modified H pin code, in which the cathode is not grounded to the case. In addition to the UV LEDs on this page, Thorlabs also offers a selection of other LEDs in the 245 - 4600 nm spectral range.

What is proper LED controller model for LED255J UV LED?

dpossin (posted 2020-10-21 10:45:40.0)

Dear Pawel, Thank you for your feedback. Unfortunately we do not offer LED controllers for our unmounted LEDs. A proper LED controller needs to have a quite stable current output and at least 100mA @ 10V.

I sell ~ 100 of the TO-39 ball lens UV LEDs/yr. Are there any discounts for resellers?

Dear colleagues! We want to buy UV-LED with wavelength 255 nm to supply our measured equipment. For this purpose we plan on getting next components: 1. UV source with Ball Lens - LED255J 2. SM1-Threaded Mount for TO-39 - S1LEDM 3. Passive-Heatsink - HSLT2 4. Lens Mount with Internal and External SM1 Threads for connection with Passive-Heatsink - LMR1S/M. We ask you to check our choice and to clear for us one problem. We plan on creating UV source with power supply via USB 2.0. However we can’t understand how we can reliably to do the mount between USB cable and LED. What kinds of additional elements are we need? Also please send me your e-mail for fast communication. Ivchenko Aleksey

These Collimated LEDs are compatible with the standard and epi-illumination ports on the following microscopes: Olympus BX/IX (Item # Suffix: -C1), Leica DMI (Item # Suffix: -C2), Zeiss Axioskop (Item # Suffix: -C4), and Nikon Eclipse (Bayonet Mount, Item # Suffix: -C5).
Typical power when used with MM Fiber with Ø400 µm core, 0.39 NA.
Our Multi-Wavelength LED Sources are available with select combinations of the LEDs at these wavelengths.
Typical power for LEDs with the Leica DMI collimation package (Item # Suffix: -C2).
Minimum power for the collimated output of these LEDs. The collimation lens is installed with each LED.
Typical power for LEDs with the Olympus BX and IX collimation package (Item # Suffix: -C1).
Typical power for LEDs with the Nikon Eclipse collimation package (Item # Suffix: -C5).
Percentage of LED intensity that emits in the blue portion of the spectrum, from 400 nm to 525 nm.

Typical values unless otherwise noted.
At 100 mA unless otherwise noted.
Temperature: 25 °C
The Lifetime is defined as the time required for the LED light output to drop by 50% when driven at 100 mA.
Because these LEDs can generate up to 1 W of heat, we recommend that they are mounted in an S1LEDM LED mount with a passive HSLT2 heat sink lens tube.

LED Mount Compatibility
Item #	LED Package	External Mounting Threads	Compatible Spanner Wrenches
Item #	LED Package	External Mounting Threads	Mount	LED Retaining Ring
S05LEDM	TO-18, TO-39, TO-46, and T1-3/4^a	SM05 (0.535"-40)	SPW603 SPW801	SPW301 SPW801
S1LEDM	TO-18, TO-39, TO-46, and T1-3/4^a	SM1 (1.035"-40)	SPW909 SPW801	SPW301 SPW801

The LEDRGBE uses a T-1 3/4 package, but is not compatible with the S05LEDM and S1LEDM, as the four pins prevent the retaining ring from holding the LED in place.

The S05LEDM and S1LEDM LED Mounts are SM05 (0.535"-40) and SM1 (1.035"-40) threaded, respectively. They are designed to hold any of Thorlabs' TO-18, TO-39, TO-46, or T1-3/4 packages using the included adapter rings. The external threading on these mounts allows them to be used in a wide variety of SM05- or SM1-compatible optomechanics.

To aid in threading the retaining ring into the mount or in threading the mount into a mating component, we recommend using our selection of spanner wrenches. The SPW801 Adjustable Spanner Wrench can be used to thread LED retaining rings into the mount and the mount into a mating component. Alternatively, the table to the right also lists the compatible fixed spanner wrench for each mount.
