Thorlabs' M660L2-C3, Deep Red, Collimated LED Assembly can be easily connected to standard and epi-illumination port on Nikon Eclipse (Bayonet Mount) Microscopes. This collimated LED consists of a high-power mounted LED and a lamphouse-port-compatible housing that contains an aspheric collimation optic. The collimation of the beam can be adjusted by changing the postition of the aspheric lens with respect to the LED. Interchanging LEDs is easy; simply unscrew one LED from the housing and replace it with a different mounted LED (purchased separately).

The LED package is in direct contact with the heat sink. Consequently, the degradation of optical output power by increased LED temperature has been minimized. If the LED is driven with a DC2100 or DC4100 controller, the integrated EEPROM chip will identify the LED and allow the controller to automatically set the proper current limits in order to protect the LED from being overdriven.
