LED Light Sources for Fluorescence Microscopy and Custom Optical Systems

The LED Light Source is intended for epi-illumination (fluorescence, reflection) or trans-illumination (bright field, phase contrast, DIC) in upright and inverted microscopes and custom optical configurations.  It can have a 10W white chip or an up to 5W single-color chip; a wide selection of colors is available.  This single compact unit contains the LED chip on a heatsink and a constant current driver; it screws into a collimator, which has a microscope-specific mount.  Intensity is controlled manually with a knob; on-off switching can be controlled by a TTL trigger signal.  Intensity and uniformity of illumination are characterized by images and acquisition parameters on standard fluorescent slides.

White light sources require 15V power supply, single color light sources can use 12V or 15V power supply.

Switching time is 25μs if 1A constant current driver is used.
