Abstract：FTIR spectrometer detectors have different instrument response function in different wave band.In application, no matter absolute or relative intensity of spectrum the authors use, the authors should calibrate the instrument with standard blackbody to find the instrument response function.In the present paper, the authors study the instrument response function of detectors (InSb detector and MCT detector) in Canada MOMAN MR154 FTIR spectrometer.The authors found the law of the change in instrument response function with temperature (radiation brightness).It is important for FTIR spectrometer calibration.
