An image intensifier tube is provided. The image intensifier tube has a microchannel plate (MCP), a photocathode and phosphor screen deposited on a fiber optic substrate. A first spacer is positioned between the microchannel plate and the fiber optic substrate. A second spacer is positioned between the fiber optic substrate and the photocathode. The first and second spacers cooperate to provide a spatial relationship among the MCP, phosphor screen and photocathode for effective operation of the image intensifier tube.
