1. A high power illumination system for a microscopy device comprising:
- a solid state illumination source comprising a plurality of light emitting diode (LED) light sources;
a diffusing collection lens comprising a diffusing surface configured to collect and diffuse light emission from the solid state illumination source, and an emitting surface disposed substantially opposite the diffusing surface;
an optical coupling element is configured to couple the light emission from the diffusing collection lens emitting surface along an optical axis to an optical output; and
a dichroic beam-splitter/combiner configured to direct emission from each of the plurality of LED light sources along a common optical axis to an optical input of the microscopy device.

Abstract
A high power microscopy illumination system is disclosed, including a solid state illumination source. A diffusing collection lens having a diffusing surface is configured to collect and diffuse light emission from the solid state illumination source. An emitting surface is disposed substantially opposite the diffusing surface. An optical coupling element couples the light emission from the diffusing collection lens emitting surface along an optical axis to an optical output. The diffusing collection lens provides improved uniformity of illumination with direct coupling, without significant power loss.
