Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light. These optically anisotropic materials are said to be birefringent (or birefractive). The birefringence is often quantified as the maximum difference between refractive indices exhibited by the material. Crystals with non-cubic crystal structures are o… WebSee Page 1. fluorite (cubic system), garnet (cubic) Minerals which are part of hexagonal, tetragonal, orthorhombic, monoclinic, and triclinic systems are optically anisotropic.
