  • Abstract
    Both SI units, the candela and the kelvin were originally derived from standard blackbody sources. Recently, instead of source-based calibrations, they both have been realized with optical detector standards. Recent decrease of the measurement uncertainties in detector-based calibrations resulted in improved uncertainties in these SI units.
