OptiGrafix™ QW and QWEP Grade Films are high clarity, chromatic quarter-wave plates made from a single layer of polymer film. Therefore QW & QWEP Grade film products have superior light transmission and dimensional stability. They are more economical than traditional PVA laminates because QW Grade film can serve as both a retarder layer as well as a protective base film. Our QW & QWEP Grade Film products 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.

QWEP Grade Films are high performance, with high heat resistance up to 150 degrees C. This grade of retarder contains no plasticizers or anti-block additives so transparency is maximized while haze and light scattering is minimized. In addition this film will not yellow over time and can withstand high lux and temperature exposure without shifts in its optical properties.

QW Grade Films are an excellent high clarity general purpose product for use in room temperature applications.

Our Quarter-Wave Optical Film can be custom manufactured to meet specific customer requirements.

Manufactured to custom levels of birefringence up to 200nm.

Custom manufactured film with additives such as color filter dyes, pigments, fluorescent dyes, optical brighteners, UV inhibitors and other additives available.
