Fresnel retarder

Fresnel rhomb achromatic retarder is available in 3- and 5-mm clear aperture diameters and mounted in 2.5-in.-diameter divided-circle rotating mount. Useful frequency range is 0.4 to 2.0 µm. Total internal reflection produces retardation between polarizations in and perpendicular to the incidence plane.
