Abstract

A far infrared spectrograph is described. The mounting is of the Czerny-Turner type. The radiation sources are a heated platinum strip used in the short-wave region and a high-pressure mercury lamp used in the long-wave region. Golay cells with diamond or quartz windows are used as detectors. Holders for filters to eliminate short-wave radiation and for reflection or transmission samples are designed for convenient use. Special chambers provide optical paths for long gas cells and provide holders for small solid samples. All parts of the optical system are in a vacuum tank and are remote-controlled. Spectra are automatically recorded on a strip-chart recorder. Spectra in the region from 18 microns to about 1 mm, obtained with six echelette gratings, are shown.

Reproducibility of wavelength settings is one part in 5000. Resolution of better than 0.5 cm−1 throughout the entire spectral region has been achieved.
