HOW MUCH YOU NEED TO EXPECT YOU'LL PAY FOR A GOOD BIREFRINGENT CRYSTAL

Each time a beam is refracted at the floor of the birefringent crystal, the refraction angle will depend on the polarization path. An unpolarized light beam can then be split into two linearly polarized beams when hitting surfaces of the fabric with non-normal incidence (double refraction).Similarly, the polarization point out of a laser beam insid
