Description
- Thinner than multiple order
- Less than 8 order
- Less temperature and wavelength dependent than multiple order
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.
