This compact device is the ideal external light source for fluorescence excitation in microscopy. Coupling is preferably
achieved via liquid light guides. The average service life of a lamp is 2,000 hours. The optimised internal air flow cools the lamp and enables quiet operation. A resettable operating hour meter shows lamp operating hours. The brightness of the lamp output can be varied in 5 steps (0-100%) by means of a mechanical dimmer unit. 

An ultra-fast shutter opens or closes after activation with approx. 6 ms. The shutter is actuated by means of an appliance switch, but is also possible externally by means of a remote control input or CAN-BUS connection.

This compact light source is available as a VIS or UV version in addition to a version that permits the coupling of multi-pin liquid light guides.
