CF & CFEP Grade Polymer Film/Optical Compensation Film
DLC 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:

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:
