UHP-Mic-LED-460 - Ultra High Power LED Light Source
 for Optogenetics and Fluorescence Microscopy


The Ultra High Power LED provides almost X10 increase of power in comparison with similar High power LED devices. The Ultra High Power LED ( > 36Watt) is an effective replacement of lasers and lamps in many power demanding applications, such as optogenetics, fluorescence microscopy, machine vision, chemical reaction activation and numerous others.

In Optogenetics the LED can be used for both in-situ and in-vivo applications. In in-situ experiments the LED can be connected to epifluorescence port of microscope, in in-vivo experiments the LED can be used with fiber coupler adaptor to enable opsin activation through fiber optic ferule in freely moving animals.

In fluorescence microscopy such markers as GFP, Quantum dots and other blue wavelength excitation markers can be used with this ultra-high power LED light source. The 460 nm LED will supply the needs of such power hungry methods as Photostimulation of Channelrhodopsin (ChR1, ChR2), FISH and FRAP.

This member of the modular Optiblocks family provides >1.7 Watt of collimated LED power on its output and 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.
