Представлены характеристики криогенного радиометра и монохроматического источника излучения, входящих в состав Государственного первичного эталона единиц абсолютной и относительной спектральной чувствительности в диапазоне длин волн от 0,25 до 14,00 мкм ГЭТ 213-2014 и предназначенных для калибровки приемников излучения по спектральной чувствительности к потоку излучения.
The primary measurement standard of absolute and relative spectral responsivity in spectral range from 0,25 to 14,00 μm was designed by the VNIIOFI in 2014. The metrological specifications and design descriptions of the facilities included in the primary measurement standard are presented. The descriptions of operating principle of the electrical-substitution cryogenic radiometer as well as the method of power spectral responsivity scale realization are given. The technical specifications of cryogenic radiometer and monochromatic source included in the facility for photodetectors power spectral responsivity calibration are given.
