  • Patent number: 4544441
    Abstract: A bolometric radiation detector wherein the electrically-conductive measuring layer is applied to a carrier film which is supported by a frame. To produce a bolometer of this type the carrier film is produced as a layer on a base material, preferably by anodic or thermal oxidation of the base material. The measuring layer is applied to the carrier film. After providing the base material and the measuring layer with a photoresist layer, the conductors are etched out and a window is made from the reverse side. The carrier film with the measuring layer structure then remains. The parts of the base material that have not been removed serve as a frame for the carrier film.
