ABSTRACT:
A light-sensitive target for a color television system which includes a transparent carrier plate such as the front plate of a color television camera, having discrete strips of interference filter material disposed thereon. The strips are disposed in parallel relation on the inside surface of the transparent carrier. An intermediate layer is formed over these strips to eliminate abrupt or sharp edges presented by the strip to the inside surface of the tube. A conductive layer is formed over the intermediate layer and finally a light sensitive medium is disposed over the entire inside surface of the system. By means of the intermediate layer, the contour between the light-sensitive and the conductive layers are caused to have generally rounded configurations, thereby eliminating interferences.
