AbstractI have measured the refractive index of zinc selenide for wavelengths between 8 and 12 mum and temperatures from 85 to 300 K. Each measurement was made by finding the deviation angle of a beam perpendicularly incident on a right triangle prism. The resulting data curves are fitted to polynomials for the temperature dependence and to three different dispersion formulae for the wavelength dependence. I achieved accuracies in the refractive index of ±0.0008 and my results agree well with most previously available data. Refinements to the previously established experimental procedure and error analysis are also presented.
