The difference in the function of the relative spectral sensitivity of the photodetector of the Luxmeter is corrected by a system of light filters to match the function of the relative spectral luminous efficiency of monochromatic radiation for daytime vision V (λ) according to GOST 8.332.
The effective reference plane of the Luxmeter coincides with the front plane of the cosine attachment of the photodetector.
