ABSTRACT:
The correction filters which are used in manufacturing the structure of phosphor areas on the screens of color picture tubes are made more effective by being silvered or aluminized and provided with optical antireflection coatings. Owing to the resulting reduction of both the exposing and the cooling times, the number of lighthouses required for a certain production volume can likewise be reduced.
