摘要： An exposure lighthouse for use in printing screen structures for cathode-ray tubes comprising a lens assembly including a diffracting optical element, a main intensity-correction filter and a supplemental intensity-correction filter in series with the main filter. Both of the filters comprise preformed carbon particles in a light - transmitting binder.

摘要： A method for preparing a supplemental intensity-correction filter for an exposure lighthouse that is used to print viewing-screen structures for cathode-ray tubes. The method involves printing a screen structure without a supplemental filter, calculating how incremental areas of the light field must be modified at the surface of an optical element of the lighthouse to produce the desired screen structure, and then printing a supplemental filter on that surface having the transmission characteristics necessary to modify the light field as required.
