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… WebNov 13, 2015 · Addition of retardation plates (often termed compensators) can change the colors and hues of a material and provide information about specimen thickness and the order or birefringence.
