Light passing through a crystal of calcite is refracted into two rays, which are separated by a wide margin due to the strong birefringence of the crystal.

A mathematical description of wave propagation in a birefringent medium is presented below. Following is a qualitative explanation of the phenomenon. The simplest type of birefringence is described as uniaxial, meaning that there is a single direction governing the optical anisotropy whereas all directions perpendicular to it (or at a given angle to it) are optically equivalent. Thus rotating the material around this axis does not change its optica…

WebSapphire is a uniaxial crystal, and its optical axis is the c-axis 〈 0001 〉. Therefore, it has birefringence, and birefringence appears when light is incident from a direction at an angle to the optical axis.
