Abstract
RECENTLY, Bhagavantam and Krishnamurty1 investigated the variation with temperature of the stress-optical constants (q 11–q 12) and q 44 of a few alkali halide crystals, using Babinet and Rayleigh compensator methods. In continuation of these investigations, we have now undertaken the study of the variation with temperature of the stress- and strain-optical constants of a number of cubic crystals in the temperature range 30–300° C., for the wavelength 5890 Å. This communication gives the outline of the method and the results obtained in the case of sodium chloride.
