ABSTRACT:
In an image intensifier tube comprising a photosensitive layer an insulating wall portion is coated with a layer of chromium oxide which is deposited in the form of a chromium nitrate layer which is subsequently baked at a temperature of approximately 525.degree. C. A thin, suitably adhesive, uniform and transparent coating layer having a comparatively high resistance value is thus achieved.
