Made from high quallity optical grade crystalline quartz quarter wave and half wave retardation versions available suitable for high and low power laser applications. Rotate the direction of polarization (λ/2) or convert linear into circular polarization or vice versa (λ/4). EKSMA OPTICS quartz retardation plates are supplied mounted and have multilayer dielectric anti-reflection coating on both sides maximising transmission.
