WebMay 20, 2016 · Optical Birefringence. Many transparent solids, such as glass, are optically isotropic, which means that their index of refraction is equal in all directions throughout the crystalline lattice of the substance. … WebOct 5, 2007 · The principal axes of the crystal ( z1, z2, z3) are oriented in such a way that the z2 -axis is contained in the interface and the optic axis z3 forms an angle θ with the interface. The projection of the optic axis on the interface is in the z -axis direction ( Fig. 7) and x ˘ is the unit vector normal to the interface.
