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.
