CF & CFEP Grade Polymer Film/Optical Compensation Film

XBH CF and CFEP Grade Optical Polymer Films are uniaxial, chromatic optical compensation films, manufactured to fractional quarter wave levels of in-plane birefringence. These single layer, high clarity, high transmission films are an economical solution to improving contrast and viewing angles of various Liquid Crystal Display modes. They is also can be used to reduce off axis light leakage in cross polarizer applications.

CF Grade films are an excellent high clarity general purpose film for use in room temperature applications. CF Grade Films are manufactured to customer specified levels of birefringence:

Available Thickness

OPD Range

.003":

25nm -100nm  ± 10nm

.005":

20nm - 100nm ± 10nm

Standard Widths: 20+", available up to 45+"

CFEP 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 andlight scattering is minimized. Further this film will not yellow over time, and can withstand high lux and temperature exposure without shifts in its optical properties. CFEP Grade Films are manufactured to customer specified levels of birefringence:
