|---|
| Optical grade is of the best optical characteristics among our products. Applied to laptop displays and light guide panels inside LCD monitors, it is of high brightness and transparency. Minimized transmissivity decline due to yellowing by minimizing thermal deformation in processing, and secured excellent weatherability by restraining environment-dependent variations in a long term usage.&& |
