The design of prisms utilizing total internal reflection to achieve particular phase retardation is considered. Two prisms are discussed that bend light by 90° without changing its polarization. Optimum design for Fresnel rhombs is considered, and designs for quarter-wave and half-wave are presented. The effect of light beam divergence and prism dispersion is treated.
