[China Glass Net] AR-Anti-reflection glass is also known as enhanced glass or anti-reflective glass. It is a special treatment of the glass surface to increase the light transmission properties of the glass. The principle is to use the interference effect produced by different optical material film layers to eliminate incident light and reflected light, thereby improving the transmittance, and there are two-sided or double-sided processes.
AR glass features:
AR glass has a high transmittance and a very low reflectance. Transmittance can reach 99% at a certain peak, reflectivity <1%. AR coated anti-reflective glass has a lower reflectance than ordinary glass, ordinary glass in the visible range, single-sided reflectivity is about 4% The total spectral reflectance is about 8%.
Advantages of AR glass
1. High visible light transmittance 99% of visible light transmittance exceeds 95%, which greatly increases the original brightness of LCD and PDP and reduces energy consumption.
2. The average reflectance is lower than 4%, and the lower value is less than 0.5%, which effectively weakens the lack of whiteness caused by the strong light behind and enjoys clearer image quality.
3, the color is more beautiful, the contrast is stronger, the image color contrast is more intense, and the scene is clearer.
4, anti-ultraviolet, effectively protect the eye's ultraviolet spectral region transmission rate is greatly reduced, can effectively block the damage of ultraviolet rays to the eyes.
5, high temperature resistant AR glass temperature > 500 degrees (usually acrylic can only withstand temperature 80 degrees)
6, scratch resistance and wear resistance AR glass film layer hardness is comparable to glass, greater than 7H, (generally PC board hardness is about 2H to 3H).
7, can withstand a variety of cleaning agents to clean acid and alkali cleaning agents, the film is not damaged.
8, impact resistance of 3mm thick glass impact performance equivalent to 6mm acrylic.
9, to maintain the viewing angle of general acrylic after installation, the viewing angle will become smaller; and after the AR glass is installed, the viewing angle will not become smaller.
10, the appearance AR glass surface flatness is far better than the coating acrylic, and the larger the size, the more obvious the difference.
11, AR glass cold and hot deformation can be omitted, suitable for all kinds of environments; at the same time, AR glass has a glaze, the appearance is more beautiful
Main application: Mainly used for display device protection screens such as LCD TV, PDP TV, laptop computer, desktop computer display, high-grade instrument panel, touch screen, photo frame glass, etc. to improve the transmittance and reduce the reflectivity of electronic products.
