Thin-film Radiation Detector

A method of operating a thin-film radiation detector such as a superconducting single photon detector comprising the steps of selecting a first polarization state of an incident beam of radiation; and directing the resulting first polarized beam of radiation at the thin- film detector surface such that the beam axis is oblique to the plane of the detector surface and the first polarized beam has an s-polarization state relative to the absorption surface of the detector. A thin-film radiation detector (1) comprises an absorbing thin film (3) material on a substrate (2); and coupling optics (4) having means for receiving an incident beam of radiation, a polarizer (16) configured to select a first polarization state of the incident beam of radiation to form a first polarized beam; and means (7) for directing the polarized beam of radiation at the absorbing thin-film material surface such that the beam axis is oblique to the plane of the detector surface and the first polarized beam has an s- polarization state relative to the absorption surface of the detector.
