  • Filters for photo-detectors
    Patent number: 4158133
    Abstract: Optical filters are directly mounted on the surface of photo-detectors. The filters have maximum radiation permeability for the operating range of the photo-detector. For that region of the spectrum which lies outside of the operating range, the filters are of maximum impermeability and considerably decrease interfering currents resulting from the incidence of foreign light. The direct mounting of the filters on the detector surface effects not only technical but also economical advantages.
