Example Embodiment
[0067] The preparation method of the above-mentioned anti-reflection glass comprises the following steps:
[0068] S10 , providing an aluminosilicate glass substrate 10 .
[0069]Preferably, the thickness of the aluminosilicate glass substrate 10 is 0.4-0.7 mm.
[0070] Preferably, the refractive index of the aluminosilicate glass substrate 10 is 1.50˜1.52.
[0071] Preferably, the aluminosilicate glass substrate 10 is cleaned and dried first.
[0072] S20, the surface of the cleaned aluminosilicate glass substrate 10 is sequentially magnetron sputtering to deposit the first low refractive index layer 20, the first high refractive index layer 30, the second low refractive index layer 40, the second high refractive index layer 50, The third low refractive index layer 60, the third high refractive index layer 70, the fourth low refractive index layer 80, the fourth high refractive index layer 85, the fifth low refractive index layer 90, and the fifth high refractive index laye...

[0105] Example 1
[0106] The structure of the anti-reflection glass of Example 1 is glass substrate / SiO 2 / Nb 2 O 5 / SiO 2 / Nb 2 O 5 / SiO 2 / Nb 2 O 5 / SiO 2 / Nb 2 O 5 / SiO 2 / Si 3 N 4 Among them, " / " represents a laminated structure, and the numerical value in parentheses represents the thickness, which is the same in the following embodiments.
[0107]The material of the glass substrate of Example 1 was aluminosilicate glass, and the thickness was 0.7 mm.
[0108] The anti-reflection glass of Example 1 is used to measure its full-band transmittance and reflectivity in the visible light range of 380-780nm by using Nippon Denshoku's SD-6000. Reflectivity≤1%.
[0109] The anti-reflection glass was tested for hardness using a pencil hardness tester, and the result was a hardness of 7H.
[0110] A certain amount of the anti-reflection glass was taken and soaked in a NaOH solution with a concentration of 10 wt % and a temperature of 40° C. fo...

[0113] Example 2
[0114] The structure of the anti-reflection glass of Example 2 is glass substrate / Nb 2 O 5 / SiO 2 / Nb 2 O 5 / SiO 2 / Nb 2 O 5 / SiO 2 / Nb 2 O 5 / SiO 2 / Si 3 N 4
[0115] The material of the glass substrate of Example 1 is aluminosilicate glass, and the thickness is 1.1 mm.
[0116] The anti-reflection glass of Example 2 is used to measure its full-band transmittance and reflectivity in the visible light range of 380-780nm by using Nippon Denshoku's SD-6000. Reflectivity≤1%.
[0117] The anti-reflection glass anti-reflection film layer was tested for hardness using a pencil hardness tester, and the result was a hardness of 7H.
[0118] A certain amount of the anti-reflection glass was taken and soaked in a NaOH solution with a concentration of 10 wt % and a temperature of 40° C. for 2H. The spectrum of the sample after immersion is tested. Compared with the spectrum before immersion, the degree of coincidence is very good; t...
