HELPING THE OTHERS REALIZE THE ADVANTAGES OF BIREFRINGENT CRYSTAL

Whenever a beam is refracted at the floor of a birefringent crystal, the refraction angle is determined by the polarization path. An unpolarized mild beam can then be break up into two linearly polarized beams when hitting surfaces of the fabric with non-standard incidence (double refraction).Equally, the polarization state of a laser beam in a ver
