Ultra-High-Power Collimated LEDs for Microscopy

               Click to enlarge

The Ultra High Power (UHP) LED provides significant increase of power in comparison to High power LED devices. The Ultra High Power LED (> 50 Watt) is an effective replacement of lamps in fluorescence microscopy, Optogenetics in-vitro, patterned illumination, confocal microscopy and numerous others.

Fluorescence microscopy applications will benefit from highly homogenous and flat field illumination. The controller features fast Optically Isolated TTL input for synchronization with the camera.

The UHP-Mic-LED can be used with a full range of other optical OptiBlocks such as Fiber Coupler, Liquid Light Guide coupler, Beam Combiner, Filter Wheel, Beam Switcher and others.
