◦As the entrance, exit and reflecting surfaces are processed to provide high parallelism and to minimize beam deflection.
◦When the linear polarization orientation of incident light is 45 degrees against the sides of square faces, the specified optical retardation will be obtained. The light will exit as linear polarization with –45 degrees orientation for the half waveplate, and as circular polarization for the quarter waveplate.
