Abstract: AN EXPOSURE DEVICE FOR PROJECTING APERTURE PATTERNS FROM A MASK ONTO A PHOTOSENSITIVE LAYER ON A CARRIER USED IN MANUFACTURING PICTURE SCREENS OF CATHODE-RAY TUBES. THE PORTIONS OF THE PHOTOSENSITIVE LAYERS EXPOSED TO LIGHT HARDEN WHILE UNEXPOSED PORTIONS DO NOT, AND ARE THEREFORE MORE EASILY REMOVABLE. IN THE FORM SHOWN, THE DEVICE COMPRISES AN ELONGATED LAMP, A LENS FOR CORRECTING DIFFERENCES BETWEEN LIGHT AND ELECTRON RADIATION SOURCES, AND AN INTERMEDIATE MEMBER HAVING AN ELONGATED APERTURE POSITIONED BETWEEN THE LAMP AND THE LENS WITH THE LONGITUDINAL AXIS OF THE APERATURE ORTHOGONAL TO THE LONGITUDINAL AXIS OF THE LAMP CONCAVE. CYLINDRICAL MIRRORS ARE USED TO REFLECT THE LIGHT SO THAT THE ACTUAL WIDTH OF THE LAMP IS EFFECTIVELY INCREASED.
