Abstract

PURPOSE: To obtain a high quality filter fit for the pickup tube of a color television set by forming org. thin films on a transparent substrate, dyeing the films with dyes to form a dyes film substrate, and heat treating the substrate.
CONSTITUTION: Org. thin films 2, 3, 4, etc. are formed on the same plane of transparent substrate 1 and dyed with dyes to form dyed film substrate 5. For example, films 2 are dyed red to form a red striped dyed film, films 3 are dyed green to form a green striped dyed film, and films 4 are dyed yellow to form a yellow striped dyed film. Substrate 5 is then heat treated for a preset time to obtain desired spectral transmittance characteristics.
