Abstract : Available data on the refractive index and its temperature derivative for alkaline earth halides were exhaustively surveyed, compiled, and analyzed. The most probable values of the refractive index at 293 K for the transparent region were generated for the materials for which experimental data were sufficiently abundant and reliable. Provisional values were also generated for the wavelength regions where available data were less abundant. Reasonable estimations of refractive index for the very scantily measured materials were made by incorporating the dielectric constants and wavelengths of absorption peaks into a simplified dispersion equation. It was found that of the twenty alkaline earth halides only seven, namely, MgF2, CaF2, SrF2, BaF2, CaCl2, SrCl2, and BaCl2, appear in the open literature with refractive index measurements.
