ABSTRACT:
A microchannel plate for an image intensifier tube, the microchannel plate comprising a substrate having an input surface and an output surface and a plurality of channels extending therebetween, each of the channels defining a channel wall, wherein the microchannel plate operates as an electron multiplier, whereby each of the channel walls emits a cascade of electrons in response to an electron entering a respective one of the channels, and a focusing element formed on an output of at least one of the channels for preventing spatial dispersion of the cascade of electrons exiting the output thereof.
