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.
