We have constructed a special purpose computer controlled system for the photo response measurement in the long wavelength infrared range, using a GPIB interface. It uses a Si-nite black body source and a monochromator with gold coated mirrors. It shows strong photon flux density in the range of interest. However the noise figures measured came out much greater than the ones quoted by the company, suggesting the necessity for the development of noise suppressing ways.
