Abstract
Measurements of the birefringence spectra for cadmium sulfide and cadmium selenide from 2.5 to 16.5 pumo btained with a rotating sample spectropolarimeter are presented. Because of the similarity in the birefringence spectra for cadmium sulfide and cadmium selenide, a highly achromatic IR retarder can be constructed from a combination of these materials. The ordinary and extraordinary refractive indices for cadmium sulfide are estimated in the region from 10.6 to 15 puman d for cadmium selenide from 10.6 to 16.5 pLmby combining these birefringence datawith an extrapolation of previous dispersion relations.
