THE SMART TRICK OF MAGNETO-OPTICAL CRYSTAL THAT NOBODY IS DISCUSSING

Any time a beam is refracted for the surface of a birefringent crystal, the refraction angle is dependent upon the polarization direction. An unpolarized gentle beam can then be break up into two linearly polarized beams when hitting surfaces of the fabric with non-standard incidence (double refraction).The reduced part with the Michel-Levy chart (
