Supplier: Newport MKS
Description: . Extremely High Bandwidth Polarization rotators are based on Fresnel rhombs, which are prisms that behave as quarter waveplates. These prisms do not depend on birefringence, instead they utilize a property of total internal reflection that produces a relative phase change

Impact of high power and angle of incidence on prism corrections for visual field loss
Distortions and reflections in the high-power Fresnel prisms used in peripheral prism placement can be considerable, and the simplifying assumption that prism deflection power is independent of angle of incidence into the prisms results in substantial errors.
