IRFS-2 calibration is related to the definition of all parameters and characteristics needed to convert the interferogram
in the input spectral radiance with required accuracy. As a result of thermal vacuum tests, systematic radiometric
error and noise equivalent spectral radiance (NESR) were obtained. In addition, instrument line shape was
measured as the spectral response of the instrument to a monochromatic radiation of CO2 laser.
Keywords: Fourier-transform spectrometer, radiometric and spectral calibration, instrument line shape measuring
