Precise Finish, Flatness and Thickness

These multiple order quarter wave and half wave retardation plates consist of a single disc of single crystal quartz or sapphire, depending on the application, which is polished to very precise finish, flatness, and thickness tolerances. They can be anti-reflective coated with a “V” coat or broadband AR coating.
