WebMar 10, 2024 · The refractive index of an isotropic mixture is measured; then the apparent refractive index of the liquid crystal is extracted using validated combination models of refractive indices in mixtures. The method was assessed with two nematic liquid crystals (5CB and MBBA) mixed with several isotropic liquids. WebThe refractive index of the ordinary ray is constant for any direction in the crystal. The refractive index of the extraordinary ray varies depending on its direction. The ordinary passes undeviating through the crystal and show normal optical properties (reflection and refraction), but the extra-ordinary ray passes deviating through the crystal.
