Extraordinary refractive indices

WebThe refractive indices for these rays (directions) — designated as o (ordinary) and e (extraordinary) — are the basic optical parameters for a uniaxial gemstone. If the o ray has a velocity in the crystal greater than … So far, we have assumed that refraction is given by linear equations involving a spatially constant, scalar refractive index. These assumptions can break down in different ways, to be described in the following subsections. In some materials, the refractive index depends on the polarization and propagation direction of the light. This is called birefringence or optical anisotropy.
