Birefringence - Wikipedia

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.
