| Zusammenfassung: | The process is used for evaluation of light exposure devices used in the production of screens for colour television cathode-ray tube. The exposure devices illuminate photo-conductive or light hardenable films in the manufacture of the phosphor regions and their interstices. Instead of the respective production film a film material of specified steepness and an intensity dynamic of at least 1.5 of intensity decades is provided. The film material must be applied up to the level of the operating film which has to be evaluated. The process assists in detecting defective forces in the production using several films. |
