A previously reported optical guided-wave method for determining the optical constants of high-index thin films has been used to measure the temperature-dependent dispersion in vacuum-evaporated cadmium sulfide thin films. Measurements were carried out over the spectral range from 4579 to 6328 Å using Ar and He–Ne lasers at 18 K, 83 K, and room temperature in an optical cryostat.
