The principles of operation and the composition of instruments incorporated into GET 156–2015, the State Primary Standard of the unit of spectral regular transmittance, unit of spectral diffuse reflectance, and unit of spectral specular reflectance in the wavelength range from 0.2 to 20.0 μm are described. The instruments are designed for reproduction and transmission of the specular regular transmittance, spectral diffuse reflectance, and spectral specular reflectance in the wavelength range from 0.2 to 20.0 μm.
