Abstract
The spectral responsivity measurement theoretical outline was demonstrated. Absolute spectral responsivity of the Silicon trap detector is calibrated with laser intensity stabilizer, closed loop refrigeration cryogenic radiometer. Seven wavelength laser beams of 476.1nm, 488nm, 514.7nm, 568nm, 632.8nm, 647.1nm and 1064nm, are chosen for the calibration experiments. Relative spectral responsivity of the cavity pyroelectric detector is calibrated in the band from 600nm to 15μm. Absolute spectral responsivity of the pyroelectric detector is transferred at 1064nm. The absolute and relative measurement uncertainty is evaluated. Results demonstrated that the absolute spectral responsivity of the Silicon trap detector and the cavity pyroelectric detector is 0.3954A/W, whose uncertainty is better than 0.04%, and 5.4E-7A/W, whose uncertainty is better than0.4%, respectively, at 1064nm. The pyroelectric detector absolute spectral responsivity uncertainty is better than 5% in other wavelength.
