Definition: | quotient of the spectral responsivity, s(λ), of the detector at wavelength, λ, and a specified reference value, sm Note 1 to entry: The specified reference value, sm, can be an average value, a maximum value or an arbitrarily chosen value of s(λ). Note 2 to entry: The relative spectral responsivity has unit one. Note 3 to entry: This entry was numbered 845-05-57 in IEC 60050-845:1987.
