Dedicated research applications in FTIR spectroscopy such as the characterization of superconductors or semiconductors usually require low sample temperatures. More precisely, the characteristic photoluminescence signals of many semiconductors compounds only appear far below room temperature because of the changed electron distribution at lower temperatures. Temperature dependent reflectance spectra of superconductor material reveal that transition temperature due to characteristic changes of the reflection spectra. Also for studies on the kinetics of chemical reactions, it can be of major importance to investigate the process over a wide temperature regime to unravel diffe
