  In this paper,absolute spectral responsivity and relative spectral responsivity of silicon trap detectors are presented.The absolute spectral responsivity calibrated with absolute cryogenic radiometer at seven wavelengths between 488nm and 1064nm.The absolute spectral responsivity scale is obtained in the spectral range from 400nm to 1100nm.The external quantum efficiency of the silicon trap detector is investigated.
