Abstract
An exposure device for the manufacture of luminescent screens for colour television tubes by photographic exposure through associated shadow masks, comprises at least two compartments of triangular section sharing a common light source. In Fig. 1, two compartments 21 and 22 for illuminating face-plates 23 and 24 through respective shadow masks 31 and 35 share a common light source comprising a lamp 27 and a reflector 38. Each compartment is provided with an individual shutter 32 and 36 so that operation is independent, and a photo-cell 42 is provided in compartment 22 to monitor the light source, and if desired, to form part of an automatic control system for eliminating changes in the light source which would affect the process. In a modification (Figs. 2 and 3, not shown), a common light source serves four compartments arranged as described in Specification 1,220,850.
