Paper Abstract

The cryogenic interferometer is an optimized sensor for low level infrared spectral measurements. An ideal application is emissivity measurements of low-temperature samples, since room temperature spectrometers become background limited by instrument self-emission in such cases. For a cryogenic instrument, operation near background limited performance for targets at 220 K with emissivity of 0.05 is possible by cooling the complete instrument to around 77 K. This instrument has been designed for operation in the laboratory, and most of the parameters are remote controlled by the data processing PC. Spectral resolution is variable from 4 cm-1 to 128 cm-1. The spectral range covered is from 600 cm-1 to 4000 cm-1. The system is built into an Infrared Lab Cryostat, providing a holding time of 48 hours. This instrument is the second cryogenic spectrometer built by Bomem, the first being the balloon-borne SIRIS, a high resolution system for atmospheric research.
