Abstract

PURPOSE:To prevent deterioration of the transparency and occurrence of multiplex reflection by using a specific rotary light-adjusting pattern having no glass base plate for the rotary light-adjusting filter of an exposure device which forms the fluorescent surface of a color image receiving tube etc. by means of the optical burning process. CONSTITUTION:This exposure device which is to form the fluorescent surface 3 of a color image receiving tube etc. by means of the optical burning process is composed of a light source 1 installed at the position corresponding to the deflection point of electron beams in the tube as completed, a stationary light- adjusting filter 4 to create the required light distribution, a lens 5 to make correction of the light path, and a rotary light-adjusting filter 6. As the rotary light- adjusting filter 6, at this time, is used a rotary light-adjusting pattern 11, in which a shutter part 9 is held at the specific part in the opaque thin disc, the rest being formed into an open window 10. Thus deterioration of transparency and occurrence of multiplex reflection can be eliminated according to this arrangement, where the stationary light-adjusting filter 4 is used in combination as a one having no glass base plate, which ensures that the conditions for manufacture of fluorescent faces can be well considered with priority.
