Get 86–2017: State Primary Standard of Units of Radiometric Quantities and Units of Spectroradiometric Quantities in the Range of Wavelengths from 0.2 to 25.0 μm

详细

The composition and metrological characteristics of GET 86–2017, the State Primary Standard of the units of radiometric quantities and units of spectroradiometric quantities in the range of wavelengths from 0.2 to 25.0 μm, are presented. The technical characteristics and operating principles of four new plants which were introduced as components of the standard to increase the precision of reproduction and transmission of the unit of spectral density of radiance, unit of spectral density of radiant intensity, and unit of spectral density of irradiance, as well as for the purpose of reproduction and transmission of the unit of the spectral density of the total radiation flux, unit of irradiance, unit of radiance of monochromatic radiation, and unit of spectral density of the radiation flux of the excitation and emission of fluorescence are described.
