Abstract
Abstract A device for intensifying light images which includes an image intensifier tube assembly that is retrofittable to two different existing housings. There is a first electrical contact for electrically connecting to electrical supply contacts when positioned in the first different housing and a second electrical contact for electrically connecting to electrical supply contacts when positioned in the second different housing. The tube assembly has first spacer for effecting a predetermined spacing between the tube assembly and the first housing when positioned in the first housing, and a second spacer for effecting a predetermined spacing between the tube assembly and the second housing when positioned therein. The first spacer is inactive to control spacing when in the second housing and the second spacer is inactive for controlling spacing when in the first housing.
