A radiation shield for near-infrared detectors of the type used in Raman spectroscopic systems comprises a chamber enclosing the detector and a cooling device in thermal contact with the chamber and the detector to reduce the level of unwanted radiation to which the detector would otherwise be exposed. The chamber may include a window in optical alignment with the detector, and the window may include one or more coatings to pass wavelengths in a range of interest or block radiation at wavelengths outside of this range. The shield may be enclosed in an evacuated dewar having a window which may also include one or more coatings to favor the wavelength range.

Provided is an infrared sensor wherein a large temperature difference can arise between the two temperature sensor devices for detection of infrared rays and for temperature compensation; minimization of the size thereof is easily possible; and the cost of the structure thereof is low. The infrared sensor comprises: an electrical insulating film sheet 2; first temperature sensor device 3A and second temperature sensor device 3B which are provided on one side face of the electrical insulating film sheet 2, and are located at a distance from each other; first foil conductor patterns 4A which are formed on one side face of the electrical insulating film sheet 2, and are connected to the first temperature sensor device 3A; second foil conductor patterns 4B which are formed on the one side face of the electrical insulating film sheet 2, and are connected to the second temperature sensor device 3B; and an infrared reflector film 6 which is provided on the other side face of the electrical insulating film sheet 2, and is opposite the second temperature sensor device 3B across the electrical insulating film sheet 2.
摘要:
We disclose a method for securing an infrared transmissive polymer to integrated panels, deadfronts, or transition plates, thus providing a reinforced polymer window through which the thermographer can scan an energized unit without being directly exposed to contact with internal components or having to remove said panels, deadfronts, or transition plates. We also disclose a device for securing the polymer consisting of a retention frame with half shear retainers that keep the polymer locked in place.

摘要:
A bolometer is described. A bolometer includes a superconductor-insulator-semiconductor-superconductor structure or a superconductor-insulator-semiconductor-insulator-superconductor structure. The semiconductor comprises an electron gas in a layer of silicon, germanium or silicon-germanium alloy in which valley degeneracy is at least partially lifted. The insulator or a one or both of the insulators may comprise a layer of dielectric material. The insulator or a one or both of the insulators may comprise a layer of non-degenerately doped semiconductor.
