The optical constants of Se and CdTe have been measured in the far ir from 10 cm−1 to 100 cm−1 using Fourier transform spectroscopy. An oscillator model has been fit to the available data for both materials over the entire ir range from 10 cm−1 to 10,000 cm−1. Several three-phonon absorption peaks have been observed and identified in the absorption spectra of Se. The linear optical properties of these important ir materials have been summarized throughout the ir region.
