摘要： This invention provides a color CRT screen exposing apparatus which collects light very effectively to make the most of the light for exposure and, more particularly, provides an improved exposing apparatus wherein the shape of light source can be easily arranged as desired resulting high and uniform illuminance on the faceplate. For this purpose, this invention comprises a housing with an opening at the center of its top whereon a faceplate for a color CRT is placed, as well as a lamp assembly for producing light, collecting means for collecting the light and a light transmission medium made of optical fiber or acrylate for transmitting the light from the collecting means to the inner surface of the faceplate.
