Why is it important?
It is a necessary requirement in infrared radiometry and spectrometry to have effective and precise filtering for the elimination of unwanted broadband radiation. Detailed knowledge of the temperature dependent spectral characteristics of both the layer and substrate materials is therefore clearly necessary for the successful design and fabrication of high performance filters for use at cryogenic temperatures.
