ABSTRACT:
Optical signal detection apparatus suitable for use in diffuse infrared light wave communication comprises an aspherical lens in combination with a photodetector. The lens comprises a body of light transparent material having a planar back surface and an aspherical front surface. The front surface is of a shape approximating a hyperboloid. A light transparent, electrically conductive coating is applied to the planar back surface of the lens, and an optical filter is disposed between the lens and the photodetector.
