  • X-ray image intensifier tube with carbon-reinforced plastic foil entrance window
    Patent number: 4855587
    Abstract: An X-ray image intensifier tube comprises an entrance window which is composed of a carbon fibre reinforced plastics foil which is covered with a metal layer. The plastics foil has a comparatively low absorption and the metal layers can be constructed so as to be sufficiently thin and from suitable materials such that only a low absorption occurs therein. The metal layers ensure that the entrance window is suitably vacuumtight and allow for simple vacuumtight connection of the entrance window to the further envelope.
