Modular Fibre-coupled LED Light Sources from 365 to 630 nm   

Prizmatix Fibre-coupled High & Ultra High Power LED Devices   

The fibre-coupled Ultra High Power LED series provides almost x10 increase of power in comparison with regular high-power LED devices. The Ultra High Power LEDs are an effective replacement of Mercury and Xenon lamps as well as lasers in many power-demanding applications such as fluorochrome activation in optogenetics, photocycle kinetics, fluorescence microscopy, chemical reaction activation, uncaging and numerous others.

Prizmatix’s Ultra High Power LED head features built-in adjustable aspheric collimator to provide collimated beam suitable for direct connection to the epi-fluorescence port of a microscope.

The Ultra High Power LED head can be easily modified for fibre optic applications with a specially designed Fibre Coupler adaptor for high NA fibres. This ensures maximum light coupling efficiency and makes it possible to achieve extreme light power from the distal end of fibres suitable for optogenetics applications.
