AR anti reflective window

AR high transmittance anti reflection glass, also known as high transmittance glass or anti reflection glass. It is a type of glass that undergoes special surface treatment. The principle is to process high-quality glass on one or both sides. AR high transmittance anti reflective glass has high transmittance and low reflectivity. The transmittance can reach 99% at a certain peak, and the reflectivity is less than 1% AR high transmittance and anti reflection glass has a lower reflectivity compared to ordinary glass, reducing the reflectivity of light to below 1%. Ordinary glass has a single-sided reflectivity of about 4% in the visible light range The total spectral reflectance is about 8% The anti reflection effect of glass surface in the visible light range can be achieved through two methods; A method of using the interference effect generated by different optical material film layers to eliminate incident and reflected light, thereby improving transmittance. This type of glass produced using destructive interference of light is called AR glass; Another method is to use the scattering effect of rough surfaces to convert a large amount of incident light into diffuse reflection light, which does not cause significant changes in transmittance. This type of glass produced by fine roughening is called AG glass.

The advantages of AR glass

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

2. The average reflectivity is less than 4%, and the low value is less than 0.5%, effectively weakening the image distortion caused by strong light behind

White deficiency, enjoy clearer image quality.

3. More vibrant colors and stronger contrast make the color contrast of the image 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 (usually acrylic can only withstand a temperature of 80 degrees)

6. Excellent scratch and wear resistance

The hardness of AR glass film layer is equivalent to that of glass, greater than 7H (generally, the hardness of PC board is about 2H to 3H).

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

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

9. Maintaining the viewing angle: Generally, acrylic will have a smaller viewing angle after installation; After installing AR glass, the viewing angle will not decrease.

10. Appearance

The surface flatness of AR glass is much better than that of coated acrylic, and the larger the size, the more obvious 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 glass like feel and a more beautiful appearance

Main applications

Ordinary LCD monitors and LCD TVs do not have a front windshield. The surface is easily scratched and damaged, and the viewing angle is small. After installing an AR glass, these drawbacks will be overcome. Mainly used for protecting display devices such as LCD TVs, PDP TVs, laptops, desktop computer display screens, instrument panels, touch screens, photo frame glass, and other electronic products that improve transmittance and reduce reflectivity.
