<p>PURPOSE:To provide a process for production having a high yield by forming gage lines and segment symbol pattern parts to a photosensitive resin film formed on a substrate and dyeing the same to discriminatable color tones so that the pattern parts of color separating filters are dyed to the prescribed color tones. CONSTITUTION:The color separating filter 2 is formed to the central part of the light transmittable glass substrate 1. The filter 2 is constituted of yellow stripe-like color separating filters 3a, 3b, 3c which shut off blue light and cyan stripe-like color separating filter 4a, 4b, 4c which shut off red light intersecting therewith. The gage lines 5a-5d are provided in order to fix the filter structural body 2 to an image pickup tube in the prescribed relation with the structural directivity of the electron gun of the image pickup tube in the stage of building said body to the image pickup tube. A segment symbol 6 is provided to permit the easy discrimination for the purpose of measurement and control after the manufacture of the image pickup tube.</p> |
