Abstract
A photoconductive layer which is vapor-deposited on a carrier in a television camera tube is provided with a structure of regions having at least one dimension which corresponds in the order of magnitude, measured transversely of the layer, to the transverse dimension of an image point in the layer. These regions are separated by partitions which consist of the same material as the further conductive layer, but for which the structure is such that they exhibit a comparatively low transverse conduction.
