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 is be arranged behind the target and is constructed so that it has low reflectance for incoming light. In order to prevent excessive transverse conduction, such a filter has a mosaic structure consisting of mutually insulated areas.
