Abstract
A commercial Fourier transform spectrometer scanning mechanism has been modified for operation at cryogenic temperatures. When installed in a 4 K cryostat with a multiple component blackbody calibration source and sensitive sub-Kelvin detector, the spectrometer will allow the evaluation of different scanning methods, metrology options and data compression techniques. It will also enable the study of the performance of critical optical components such as beam splitters and filters at their intended operating temperatures.
