  • Abstract
    Transmittance and reflectance measurements with Fourier transform spectrometers in the MIR and FIR can exhibit significant deviations when working with cooled detectors. By measuring at two flux levels and by using an appropriate evaluation scheme systematic deviations can be largely reduced in the range from 25 μm up to 1000 μm.
