The authors have measured the following parameters of chemical vapor deposited polycrystalline ZnSe (CVD ZnSe): refractive index and change of index of refraction with temperature (dn/dT) over the wavelength range 0.5 micrometers to 18 micrometers using the method of minimum deviation; the coefficient of linear thermal expansion and dn/dT at 10.6 $mu$m using Fizeau interferometry; and the elastic moduli and photoelastic moduli using Fizeau and Twyman-Green interferometry. A sensitive technique has been developed for measuring stress- optical constants of materials that exhibit a small stress-optical effect. (GRA)
