THE SMART TRICK OF BIREFRINGENT CRYSTAL THAT NOBODY IS DISCUSSING

Any time a beam is refracted with the surface area of a birefringent crystal, the refraction angle depends upon the polarization route. An unpolarized light-weight beam can then be break up into two linearly polarized beams when hitting surfaces of the fabric with non-ordinary incidence (double refraction).Of course, the bigger the thickness or cha
