Cryogenic temperature IR refractive indices of cesium bromide and cesium iodide

Appl Opt. 1979 Sep 15;18(18):3116-8. doi: 10.1364/AO.18.003116.

Abstract

The refractive indices and their variation with temperature and wavelength in the range 80-300 K and 2-30 microm are measured for cesium bromide and cesium iodide. The indices are also fitted using both Sellmeier and Herzberger types of equations.
