These UV LEDs are compact light sources in hermetically sealed TO-39 packages with integrated ball lenses. They provide an output power of 1 mW and have a small viewing half angle no greater than 7.5°. 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.

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.

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.

The LEDs can be mounted in Thorlabs' SM-threaded passive mounts for LEDs, such as the SM1 (1.035"-40) threaded S1LEDM. They 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 HSLT2 passive heat sink lens tube is recommended for use with the S1LEDM mount. These LEDs have a TO-39 package that follows a modified H pin code (shown to the upper left) where 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.
