               Click to enlarge

The Ultra High Power LED provides more than X10 increase of power in comparison with similar High power LED devices. The Ultra High Power LED (> 50 Watt) is an effective replacement of lasers and lamps in many power demanding applications, such as fluorescence microscopy, Optogenetics in-vitro, patterned illumination, confocal microscopy, chemical reaction activation and numerous others.

Fluorescence microscopy applications will benefit from highly homogenous and flat field illumination. The shielded UHP-T-EP LED head contains the high current driver, while the LED controller box performs control functions. This arrangement eliminates much of RFI / EMI interference common in high current light sources. The controller features Optically Isolated TTL and Analog Inputs. These features make this product especially suited for electrophysiology rig applications.

UHP-T-EP 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.
