Retarder films are used to change the state of polarized light by a predictable amount. This is accomplished through the application of a uniform birefringent film. Three different grades of retarder film are available based on the type and amount of birefringence in the film.
A quarter wave retarder has a phase shift of 90 degrees. This film converts linearly polarized light to circularly polarized light. A half-wave retarder can rotate the plane of polarization by 90 degrees. This is useful in applications with lasers which are too cumbersome to reposition.
All Retarder Films are high performance, with high heat resistance up to 60 degrees C. In addition this film will not yellow over time and can withstand high lux and temperature exposure without shifts in its optical properties. Films are easy to handle and apply in a variety of retarder applications such as circular polarizers, LCD's, fiber optics, and other coherent and polarized light applications.
