Abstract The basic principle of the realize 380~780 nm total spectral radiant flux (TSRF) scale is described, based on measuring total luminous flux and measuring relative spectral radiant intensity distribution by a goniospectroradiometer. The TSRF quantity traces to the primary standard of total luminous flux, and the primary standard of spectral radiant intensity, the high temperature black body. The measurement uncertainty components of TSRF scale include the total luminous flux, spectral radiant intensity standard lamp, the array spectroradiometer, the goniospectroradiometer (mechanics) and the repeatability. The expanded uncertainty is evaluated to be U=3.3%~1.6%, k=2。
