Abstract

An absolute spectroradiometric scale has been developed based on an electrically calibrated absolute detector and silicon detector–interference filter combination. Using the recently adopted definition of the photometric base unit, the candela, the absolute spectroradiometric scale was used to realize a photometric scale, i.e., to calibrate incandescent lamps as luminous intensity standards. These new scales were compared with existing standards and were found to agree to better than 1%.
