The use of phosphorus glass has the advantage that it is opaque to infrared radiation, so that the application of a...
1. A solid-state imaging device comprising a semiconducting imaging element with a radiation-sensitive surface, which imaging element is provided in a housing which is covered, at the side facing the radiation-sensitive surface, with a window of a transparent material which is attached to the envelope by means of an adhesive, characterized in that the transparent material includes a layer of phosphorus glass, and in that at least the side of the window facing the radiation-sensitive surface is provided with a coating consisting of a layer of chromium whi...
