Task Group on detector based standards for spectroradiometry (CCPR-WG-SP-TG18)

Strategic priority

• The use of spectrally resolving detectors as primary scale realization and transfer standards for radiometry and photometry.

Terms of reference

• To organise an interlaboratory comparison for detector-based realisation of spectral irradiance using suitable spectroradiometers as transfer standards. It should be carried out in two stages. The first stage involves an informal comparison intended to facilitate mutual learning. A pilot comparison is arranged in the second stage.
• Once the comparison yields acceptable results, make a recommendation to the CCPR regarding the acceptance of spectrally resolving detectors for primary scale realizations and as transfer standards.
