Fresnel Rhomb

Application ID: 42891

A Fresnel rhomb is a prism that uses total internal reflection to manipulate the polarization of light. In this example, light in the prism is internally reflected at an angle of incidence that induces a 45-degree phase delay between s- and p-polarized radiation. By subjecting the light to two such reflections, the prism converts incoming linearly polarized light to circularly polarized light.

This model example illustrates applications of this type that would nominally be built using the following products:
