Application of AR (Anti reflective Film) in Optical Glass

By utilizing the interference effect of nanoparticles on light, glass/touch screens can be enhanced in transparency. Single sided coating can increase the transmittance of visible light by 2-3%, while double-sided coating can achieve a transmittance of visible light of over 96%. When used in conjunction with AF/AG, it also has the following characteristics: fading, anti sweat, anti fingerprint, anti oil stains, corrosion resistance, hydrophobicity, graffiti resistance, and easy cleaning.

The advantages of AR glass

1. The peak visible light transmittance is 99%, and the average visible light transmittance exceeds 95%, significantly improving the original brightness of LCD and PDP and reducing energy consumption.

2. The average reflectance is less than 4%, with a value of less than 0.5%, effectively reducing the deficiency of whitening caused by strong light behind the scenes, and enjoying clearer image quality.

3. More vibrant colors and stronger contrast make the image color contrast stronger and the scenery clearer.

4. Anti UV, effectively protecting the eyes. The transmittance of the UV spectrum is greatly reduced, which can effectively block the damage of UV to the eyes.

5. High temperature resistant AR glass with a temperature resistance of>500 degrees (generally acrylic can only withstand a temperature of 80 degrees)

6. Anti scratch and wear resistance * * The hardness of the AR glass film layer is equivalent to that of glass, greater than 7H (generally, the hardness of PC boards is about 2H to 3H).

7. Can withstand various cleaning agents for cleaning, acid and alkali resistant cleaning agents for wiping, and the membrane layer is not damaged.

8. The impact resistance of 3mm thick glass is equivalent to 6mm acrylic.

9. Maintain the viewing angle. Generally, after installation, the viewing angle of acrylic will decrease; After installing AR glass, the viewing angle will not decrease.

10. The surface flatness of AR glass is much better than that of coated acrylic, and the larger the size, the more significant the difference.

11. The cold and hot deformation of AR glass can be almost negligible, making it suitable for various environments; At the same time, AR glass has a sense of glass and a more beautiful appearance
