Abstract
An image intensifier tube includes a photocathode ( ) with an active layer ( ) providing an electrical spectral response to photons of light. The photocathode ( ) also includes integral spacer structure ( ) which extends toward and physically touches a microchannel plate ( ) of the image intensifier tube in order to establish and maintain a desirably precise and fine-dimension spacing distance “G” between the photocathode and the microchannel plate. A method of making the photocathode and a method of making the image intensifier tube are described also.
