DEVICE FOR MEASURING PARAMETERS OF SELF-RADIATION IN IR-RANGE Russian patent published in 1995 - IPC

FIELD: IR-spectroscopy. SUBSTANCE: device has case-cryostate, inside which optical system is installed. The optical system has thermal table disposed in series with monochromator and photodetector. The thermal table is provided with unit for measuring and regulating temperature and with unit for sample fixing. Monochromator has cold screen, inside which there is a round-shaped inlet hole. Monochromator also has mirror collimator, diffraction grating, and mirror lens, which is disposed in front of the photodetector. Unit for sample fixing is disposed at focal plane of the collimator. Device allows to register weak radiations in IR-range and to measure angular and temperature relations of emissive powers of materials. EFFECT: improved precision of measurements. 1 dwg
