Wave plates (retardation plates or phase shifters) are made from materials which exhibit birefringence. The velocities of the extraordinary and ordinary rays through the birefringent material varies inversely with their refractive indices. This difference in velocities gives rise to a phase difference when the two beams recombine. CRYSMIT provides all kinds of Half wave plate ,Quarter wave plate, Octadic wave plate, or full wave plate. The advantages of CRYSMIT wave plates include quality assurance, competitive prices, ample stock, Chinese brand, online ordering, technical support, and free repairs within the warranty period. Our " Waveplates Selection Guide " will help you select a reasonable wave plate.
