A calorimetric method for measuring the absolute spectral sensitivity of a far-infrared 100 micrometers to 5 mm detector was developed. The method uses a liquid-helium-cooled integrating-sphere calorimeter capable of measuring a radiative power of the order of 1 microwatt. A preliminary sensitivity measurement of an InSb detector at 3.4 mm has been made. Author
