Apparatus for the photogeneration of electrical signals representative of a detectable condition of an image-bearing surface. The apparatus includes a transparent substrate upon which an array of spaced, thin film photosensitive elements is deposited. A substantially loss-free, light transmitting faceplate, preferably formed from a fused array of oriented optical fibers is operatively spaced from that array of photosensitive elements by a layer of optical grease.

Disclosed is an improved dual layer anti-reflective coating for use in a photoresponsive semiconductor device, and a device incorporating the coating. The coating has a uniformly low parasitic absorbance in the range of about 475 to 600 nanometers. The dual layer has an incident light layer and an intermediate layer. The intermediate layer is formed of a silicon alloy material having at least one band gap widening element incorporated therein. The index of refraction of the intermediate layer has an index of refraction intermediate the indexes of the incident light layer and the underlying photoresponsive semiconductor device.
