Abstract
Image intensifier systems incorporating a microchannel plate (MCP) and methods for producing the same are disclosed. In some examples, a device is disclosed that includes a first substrate having a radiation-receiving first surface and an opposed second surface through which electromagnetic radiation is transmitted. A second substrate is coupled to the first substrate to define a vacuum cavity therebetween. An electron-emitting photocathode is disposed within the vacuum cavity for generating electrons from electromagnetic radiation transmitted through the second surface. A microchannel plate is disposed within the vacuum cavity and defines microchannels extending from an input end to an output end. Each of the microchannels is configured to generate electrons in response to an electron generated by the photocathode being received through the input end of the respective microchannel. A phosphorescent layer also is disposed within the vacuum cavity and adjacent the output ends of the microchannels of the microchannel plate.
