Abstract

Recent developments in semiconductor physics have produced infrared detector materials with increased detectivity out to the 40 μ wavelength region of the electromagnetic spectrum, In order to realize maximum sensitivity to wavelengths above approximately 6 μ, it is necessary to cool the detecting elements to temperatures ranging from 4° to 200°K. In the 2–6 μ wavelength region, detector materials exhibit improved performance when refrigerated to a lesser degree. This paper is primarily concerned, however, with techniques of cooling these devices to cryogenic temperature levels.
