Vented header assembly of an image intensifier device

摘要

An image intensifier device and a method of fabricating the image intensifier device are disclosed. The image intensifier device includes a microchannel plate (MCP) (16) having a thin-film applied to a surface thereof. An anode assembly comprising an image sensor (43) mounted to a header (68) is positioned adjacent the MCP. A spacer (16) defining a mounting surface is positioned against a mounting surface of the header of the anode assembly for separating the MCP from the anode assembly. A recess (80) is defined in either the header (68) or the spacer (16) at the interface between the header and the spacer. The recess forms a passageway (80) defined between the spacer and the header thru which organic gases pass.
