Abstract: A sealing structure for an optical device, such as an image intensifier device, is provided. The optical device includes an evacuated housing and an anode positioned within the evacuated housing. An interior sealing member extends from the anode. An exterior sealing member extends from a component of the image intensifier device, wherein the exterior sealing member is positioned to extend adjacent to and substantially parallel with the interior sealing member such that a gap is defined between the sealing members. A seal cup is positioned for sealing engagement with both the interior sealing member and the exterior sealing member to substantially maintain a vacuum condition within the housing.

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