Abstract
The stress-optic coefficients of ZnSe have been measured at room temperature; Twyman-Green and Fizeau interferometers were used in conjunction with a four-point loading device. Test specimens were rectangular parallelepipeds of chemically vapor-deposited material prepared by Raytheon Corporation. Measurements were made with the optical propagation parallel to the deposition direction, and optical scanning and computer analysis were employed to determine fringe positions to an accuracy of better than 0.01 of a fringe spacing. The experimental values for π11 and π12 are –1.48 ± 0.05 × 10−12 m2/N and +0.22 ± 0.05 × 10−12 m2/N, respectively.
