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.
