The refractive indices of synthetic sapphire (Al2O3) were measured at selected wavelengths and the values of index range from 1.834 at 0.265 µ in the ultraviolet to 1.586 at 5.58 µ in the infrared. A three-term Sellmeier dispersion equation of the form [Equation] was fitted to the experimental data. Dispersive quantities were computed which estimate the optical performance to be expected from sapphire.
