Web• Tetragonal and hexagonal crystals all have one unique rotation axis, the c-axis, which is a 4- fold, 4, 6-fold, or 6, 3-fold, 3axis. Measurements of refractive indices for tetragonal and hexagonal crystals demonstrate that the c-axis is also a unique direction with respect to the velocity of light. 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. When light is incident parallel to the c-axis, the optical axis, the refractive index is limited to only one kind, but when polarized ...
