ABSTRACT:
A light collector for use with a photodetector that provides uniform photodetector output response over a polar angular range regardless of the polar angle of incidence of light upon the collector is disclosed. The light collector comprises a generally spheroidally-shaped light direction changer having a light diffusing surface, and a generally spheroidally-shaped polar attenuator. The geometric center of the photosensitive surface of the photodetector is adjacent to the vertex of the generally spheroidally-shaped light direction changer.
