ABSTRACT:
An image intensifier tube comprising an input screen assembly which includes a photosensitive semiconductor wafer having a substrate of one conductivity type material forming a plurality of P-N junctions with a planar array of mutually isolated islands of opposite conductivity type material, the islands protruding substantially equal distances from a common surface of the substrate, an opaque film of resistive material overlying the exposed areas of the islands and the common surface of the substrate, a layer of electroluminescent material disposed in abutting relationship with the distal ends of the islands and a layer of photoemissive material disposed in axially aligned relationship with the electroluminescent layer.
