Thorlabs offers post-mountable and SM-threaded mounts for light emitting diodes (LEDs) in a variety of LED packages and mounting configurations. The USB-Powered LED Mounts are available for our LEDs in T-1 3/4 packages and provide both mounting to SM05-threaded (0.535"-40) components. The LEDMF passive mount is compatible with TO-18, TO-18R, and T1-3/4 unmounted LEDs and allows them to be mounted on our Ø1/2" Posts. SM05-threaded (0.535"-40) and SM1-threaded (1.035"-40) passive mounts are available for LEDs in TO-18, TO-39, TO-46, and T1-3/4 packages; these SM-threaded mounts allows LEDs to be used in a wide variety of SM05- or SM1-compatible optomechanics, including our Kinematic Mounts, Lens Tubes, XY Translating Mounts, 16 mm Cage Plates (SM05 compatible), and 30 mm Cage Plates (SM1 compatible).
Mounts are also available for TO can laser diodes as well as fiber-pigtailed laser diodes.
LED Temperature Warning
Please note that these diode mounts do not have any temperature regulation or temperature measurement capability, which only makes them suitable for LEDs that do not require active cooling. For our selection of heatsink-mounted, high-power LEDs, please click here. Running an LED at a high operating temperature can significantly shorten its lifetime.

According to the tech support response to CAS-561960-Q3C0L4 the S1LEDM (SM1-Threaded Mount for LEDs) will also mount several InGaAs photodiodes (e.g. FD10D & FD05D: TO-18, FDGA05: TO-46) and yet I had to write to tech support to find this out.
Consider adding links on the photodiode pages that let users know explicitly that they can use the S1LEDM to integrate their bare photodiodes into cage and tube systems.
Thanks! ksosnowski

However yes the passive LED mounts are suitable for photodiodes also as long as the photodiode matches the TO-format size listed. cbrideau

- USB-Powered Mount for LEDs in T-1 3/4 Packages
- Options with Built-In 51 Ω or 62 Ω Current-Limiting Resistor for Different Electrical Requirements
- External SM05 (0.535"-40) Mounting Thread
- Includes Micro-B USB to USB Type-A Cable for Power LED Module
These USB-Powered LED Mounts provide both power and a mounting socket for our unmounted LEDs in T-1 3/4 packages within a single compact housing. Because of the varied electrical requirements, we offer the LED mounts with either a 51 Ω or 62 Ω current-limiting resistor. The module is powered via the micro-B USB port on the back of the housing which can be connected to a USB power source or PC via the included USB to micro-B USB cable. The housing exterior features external SM05 (0.535"-40) threading which can be used to integrate these mounts with a cage system or SM05-threaded component.
When mounting an LED, use the engraving on the housing to determine the appropriate length to cut the leads (see drawing to the right). Insert the LED with the anode lead going into the socket indicated by a (+) sign and the cathode into the socket indicated by a (-) sign. Use light force to mount the LED as excessive force may bend the electrode leads.
These powered mounts offer a fixed resistance and input voltage; choosing the appropriate mount for your LED will minimize damage to the LED. In general, a mount with a lower resistance value will increase the forward current available to the LED and proportionally increase the optical output power. However, the forward current must not exceed the maximum current of LED as this can cause permanent damage to the LED. The minimum mount resistance (R) recommended to use a desired LED is given by the following equation:
where the input voltage of the mount (VI,Source) is 5 V and the typical forward voltage (VF,Typ) and maximum forward current (IF,Max) are properties of each LED. Please consult the specifications of your LED for these values.

The LEDMF LED Mount is designed to hold any of Thorlabs' TO-18R packages directly or our T-1 3/4 or TO-18 packages using one of the included adapter rings (Ø4.7 mm adapter for TO-18 or Ø5 mm adapter for T-1 3/4). The LED is secured in the mount with a top-located cap screw with a 5/64" (2 mm) hex. The L-shaped mount has a counterbored through hole suitable for an 8-32 (M4) cap screw so that the LEDMF can be attached to a Ø1/2" Post.
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 T-1 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.
