Abstract
A photocathode device for use in an image intensifier of a night vision device, the device having a faceplate fabricated from an optically transparent material and a photoemissive semiconductor wafer bonded to the faceplate. The photoemissive wafer includes a first contact disposed on a peripheral surface thereof for electrically contacting the wafer and an annular-shaped second contact disposed on the emission surface of the wafer for enabing a potential difference to be applied across the wafer to facilitate the emission of photogenerated carriers from the emission surface.
