Claims

[Scope of utility model registration request]

In an image intensifier equipped with an input phosphor surface, a focusing electrode, an anode, and an output phosphor surface within a glass envelope, the evaporation source forming the photocathode is positioned approximately on the central axis of the focusing electrode during evaporation. a support means for rotatably supporting the vapor deposition source on the focusing electrode; a slit for allowing the supporting means to retreat outside the focusing electrode; and a slit for allowing the withdrawn supporting means to return to the focusing electrode. and an image intensifier.
