ABSTRACT:
In an image intensifier comprising an evacuated vessel with a first disk which forms an input window and on whose inner surface a photocathode is disposed, and with a second disk which forms an output window and on whose inner surface a fluorescent screen is disposed. The spacing between the first and second disks is small in relation to the diameter of the image intensifier. The input and output windows are plane-parallel, and a spacer ring is disposed between the first and second disks whose inside diameter increases from the area of the first disk in the direction of the second disk. The spacer ring is spaced at its inside diameter as close as possible to the first disk.
