A spectrally selective optical-radiation detector can be normalized to an equivalent detector having unique values for its average responsivity (formula presented) and its cut-on and cutoff wavelengths λ1 and λ2. It is shown that the radiant power of any source that is described by a second-degree polynomial can be determined exactly between limits λ1 and λ2. Calculations were made for several real detectors and Planckian radiators at several temperatures to demonstrate the low errors inherent in this scheme.
