ABSTRACT:
The optical cross-talk in a camera tube is reduced by the provision of a filter element which overlaps the entire target. The filter may be arranged in front of the photosensitive target and have a spectral transmission which is adapted to the spectral sensitivity of the target. The filter may also be arranged behind the target and preferably constructed so that it is also low-reflective for incoming light. In order to prevent excessive transverse conduction, such a filter may have a mosaic structure consisting of mutually insulated areas. Optical cross-talk may also be reduced by mounting the target on a support which is separately arranged in the camera tube and which has a small thickness.
