spectral luminous efficiency
noun
a measure of the efficiency of radiation of a given wavelength in producing a visual sensation. It is equal to the ratio of the radiant flux at a standard wavelength to that at the given wavelength when the standard wavelength is chosen so that the maximum value of this ratio is unity
Symbol: V ( λ ) ((for photopic vision)), V′ ( λ ) ((for scotopic vision))
