Abstract

We have developed measurement systems for radiometric realization of the units of luminous intensity and illuminance. The advantages of the trap-detector-based systems include a low level of detector-filter interreflections and good spatial homogeneity. Evaluation of known uncertainty components gives a total uncertainty of 0,6% (2 σ).
