Wide-angle broadband anti-reflection coated glass

Abstract

The invention relates to anti-reflection coated glass and in particular relates to wide-angle broadband anti-reflection coated glass which has a good anti-reflection effect on large-angle incident light. The wide-angle broadband anti-reflection coated glass comprises a glass substrate and an anti-reflection film arranged on the surface of the glass substrate. The wide-angle broadband anti-reflection coated glass is characterized in that the anti-reflection film sequentially comprises a first layer with a high refractive index, a second layer with an absorption property, a third layer with a high refractive index and a fourth layer with a low refractive index upwards on the surface of the glass substrate, wherein the film layer material is selected from an alloy of Ni and M, and at least one of oxides, nitrides or nitric oxides of the alloy of Ni and M; the M is at least one of Cr, Ti, Al, Si, Nb, Zr, Bi, Mo, Zn, Sn, Mn and Fe. The wide-angle broadband anti-reflection coated glass has the advantages of excellent anti-reflection effect on wide-angle oblique incident light, the film layer is simple in structure, the production process is greatly simplified, and the cost of the glass is reduced.

Description

Technical field: [0001] The invention relates to an anti-reflection coated glass, in particular to a wide-angle broadband anti-reflection coated glass which still has a good anti-reflection effect for large-angle incident light. Background technique: [0002] Anti-reflection coated glass is coated with anti-reflection film on the surface of high-quality glass by various methods such as physical vapor deposition (such as evaporation coating, sputtering coating, etc.), chemical vapor deposition, chemical sol coating (such as sol-gel method), so that The reflected light generated on the front and rear surfaces of the film interferes with each other, thereby canceling the reflected light and enhancing the transmitted light, so that the glass surface has low reflection and high transmission performance. Anti-reflection coatings are widely used in photovoltaics, optics, optoelectronics and other fields. Anti-reflection film is also very useful in the automotive field, such as bei...
