Abstract
An electron vacuum image intensifier for use in an x-ray diagnostic installation has an output screen followed by an objective lens system in the installation for connection to a picture receiving tube of a television chain. The carrier for the output luminescent screen of the intensifier is incorporated into the wall of the bulb or tube of the intensifier, and has a thickness corresponding to at least half of the diameter of the output image for avoiding reflections and improving the image quality.
