Made from high quallity optical grade crystalline quartz quarter wave and half wave retardation versions available suitable for high and low power laser applications. Retardation plates are supplied mounted and have multilayer dielectric anti-reflection coating on both sides maximising transmission. Retardation of multiple order plates is only slightly more temperature dependent comparing with the zero order ones.
