In anisotropic crystalline materials, whose optical properties are different in different directions, incident beam is split into two orthogonally polarized components propagating in a crystal with different velocities. These components are called ordinary and extraordinary rays, and they characterize different indexes of refraction: no &#x2013; for ordinary [&hellip;]</description></oembed>
