Webthe optic axis of the crystal is split into beams which are refracted by different amounts. Linearly birefringent, uniaxial crystalline materials are characterized by having a unique axis of symmetry, called the optic axis, which imposes constraints upon the propagation of light beams within the crystal. Two WebBirefringent crystal quartz plates oriented at Brewster's incidence are each cut with their optic axis lying in the face of the plate but rotated about 45° out of the incidence plane. The linearly polarized dye beam is split upon entry into the crystal into orthogonally polarized components, the extraordinary and ordinary rays.
