An X-ray image intensifier tube is constructed as a modulator system using modules which are uniform for as may different types of tube as possible. Whenever feasible, the modules are detachably combined so as to form one unit.

Modular X-ray image intensifier tube

A method of manufacturing light detection units which comprise a photocathode disposed on an entrance window, an electron detector including a semiconductor junction, and means which transmit the electrons from the photocathode to the electron detector including a perforated aperture plate disposed between the entrance window and the electron detector. The photocathode is formed on a surface of the entrance window after assembling the entrance window and electron detector to the means which transmit the electrons. Perforations in the aperture plate are covered with spherical shields while the photocathode is formed on the surface of the entrance window. The shields are then removed.
