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