Summary

A far-infrared system used to measure weak absorption spectra of gases at pressures up to a few atmospheres and at temperatures as low as 20 K is described. The principal component is a multiple reflection mirror cell, cooled either with liquid nitrogen or with the boil-off gas from liquid helium.
