LEDs with Ø1.20" heat sinks have the same outer diameter as an SM1 Lens Tube, allowing them to fit inside a 30 mm Cage System. A selection of our LEDs are mounted to larger heat sinks, as they generate more heat during operation. These heat sinks are enclosed in Ø57.0 mm vented plastic housings and include four 4-40 tapped holes on the front for integration with 30 mm cage systems. Every LED features an EEPROM chip which stores information about the LED (e.g., current limit, wavelength, forward voltage). When controlled by a Thorlabs LED driver designed to read the EEPROM chip, the data can be used to implement smart safety features. These mounted LEDs possess good thermal stability properties, eliminating the issue of degradation of optical output power due to increased LED temperature. For more details, please see the Stability tab. Please note that mounted LEDs are not intended for use in household illumination applications. LED Collimation Our adjustable collimation adapters can translate a Ø1" (Ø25 mm) or Ø2" (Ø50 mm) lens by up to 11 mm or 20 mm, respectively. Each adjustable collimation adapter includes an internal SM2 (2.035"-40) thread adapter so that the LEDs can be easily integrated with Thorlabs' SM2-threaded components, such as our Ø2" lens tubes. These adapters are offered in versions with and without an AR-coated aspheric condenser lens. In addition, microscope collimation adapters are available that incorporate an AR-coated aspheric lens. These adapters mate to the epi-illumination ports on select Leica DMI, Nikon Eclipse Ti, Olympus IX/BX, or Zeiss Axioskop microscopes. Thorlabs also offers mounted LEDs with pre-attached microscope collimation adapters. We offer suggestions for collimating most LEDs. Click on the info icon (info icon) for each LED below for details. The Collimation tab provides additional information on collimating an LED. Driver Options Thorlabs offers six drivers compatible with some or all of these LEDs: LEDD1B, UPLED, DC40, DC2200, DC4100, and DC4104 (the latter two require the DC4100-HUB). See the tables below for driver compatibility information, and the LED Drivers tab for a list of specifications. The UPLED, DC40, DC2200, DC4100, and DC4104 drivers are capable of reading the current limit from the EEPROM chip of the connected LED and automatically adjusting the maximum current setting to protect the LED. Multi-LED Source A customizable multi-LED source may be constructed using our mounted LEDs and other Thorlabs items. This source may be configured for integration with Thorlabs' versatile SM1 Lens Tube Systems and 30 mm Cage Systems. Please see the Multi-LED Source tab for a detailed item list and instructions.
