ISO/TC 211 Multi-Lingual Glossary of Terms (MLGT)

Note 1 to entry: The spectral responsivity is the response of the sensor with respect to the wavelengths dependent radiance.

Note 2 to entry: The definition is described mathematically in IEC 60050-845. The spectral responsivity is quotient of the detector output ${\displaystyle \text{d}Y\left(\lambda \right)}$ by the monochromatic detector input ${\displaystyle \text{d}{X}_{\text{e}}\left(\lambda \right)=X_{\text{e}},{}_{\lambda }\left(\lambda \right)\cdot \text{d}\lambda }$ in the wavelength interval ${\displaystyle \text{d}\lambda }$ as a function of the wavelength ${\displaystyle \lambda }$ ${\displaystyle s\left(\lambda \right)=\frac{\text{d}Y\left(\lambda \right)}{\text{d}{X}_{\text{c}}\left(\lambda \right)}}$
