Aid-base resistance anti-reflection coated glass

Abstract

The invention relates to anti-reflection coated glass, in particular to aid-base resistance anti-reflection coated glass. The aid-base resistance anti-reflection coated glass comprises a glass base board and an anti-reflection film arranged on the surface of the glass base board, wherein the anti-reflection film is composed of high refractive index layers and low refractive index layers arranged in staggered and overlapped mode. The aid-base resistance anti-reflection coated glass is characterized in that three layers in the anti-reflection film are an outmost layer, a second layer and a third layer in sequence from the outmost layer to the inner. The outmost layer is 1.9-2.4 in refractive index and 3-20nm in geometry thickness and is chosen from a nitride of silicon (Si) or at least one of oxides of titanium (Ti), zirconium (Zr) and hydrogen fluoride (Hf). The second layer is 1.4-1.7 in refractive index and 50-85nm in geometry thickness. The third layer is 1.9-2.5 in refractive index and 100-180nm in geometry thickness. The aid-base resistance anti-reflection coated glass has the advantages that the anti-reflection film is provided not only with good aid-base resistance, but also with good mechanical tolerance and a good anti-reflection effect, and the anti-reflection film is coated on a single face of glass so that reflectivity of the glass can be reduced by more than 2% and even by more than 3%.

Description

Technical field: [0001] The invention relates to an anti-reflection coated glass, in particular to an acid and alkali resistant anti-reflection coated glass. Background technique: [0002] In the production of modern optical films, the anti-reflection film is the most widely used and the largest output optical film. Without the use of anti-reflection film, due to the reflection loss of light or the high "glare" effect of the substrate, the Many instruments are not working properly. In addition to traditional photographic equipment and observation instruments, anti-reflection glass is used in museums, exhibition halls, shop window booths and solar glass. In recent years, as people's requirements for automotive glass have become higher and higher, anti-reflection glass has been widely used in automotive glass, such as reducing the reflection of instrument panels on the front screen and improving the light transmission of the front screen. , increasing its security.

Problems solved by technology

[0013] The technical problem to be solved by the present invention is to provide an anti-reflection coated glass with good acid and alkali resistance and anti-reflection effect in view of the disadvantage that the existing anti-reflection coated glass cannot meet higher requirements in terms of weather resistance
