Many radiometric, photometric, and colorimetric applications require the determination of the absolute spectral power responsivity of photodetectors. The absolute spectral power responsivity is the ratio of the photodetector's output (in amperes or volts) to the spectral radiant flux (watts) input to the photodetector. The absolute spectral power responsivity is also referred to simply as the absolute spectral responsivity. Accurate measurement of absolute spectral power responsivity of photodetectors has been a service provided by the National Institute of Standards and Technology's (NIST) Optical Technology Division and its predecessors for over 20 years.
