ABSTRACT:
An improved photocathode for use in a night vision system, comprising a glass face plate, an AlInAs window layer having an anti-reflection and protective coating bonded to the face plate, an InGaAs active layer epitaxially grown to the window layer, and a chrome electrode bonded to the face plate, the window layer, and the active layer providing an electrical contact between the photocathode and the night vision system, whereby an optical image illuminated into the face plate results in a corresponding electron pattern emitted from the active layer.
