Abstract
Description
Technical field
[0001] The invention relates to a glass anti-reflection coating solution and its application method in preparing anti-reflection glass. Background technique
[0002] When light propagates in two different media, it will reflect on the interface. According to the Fresnel reflection law, the reflectivity R = (n 1 β N 0 ) / ( n 1 + n 0 ), n 0 And n 1 They are the refractive index parameters of the two media. For glass and air, the refractive index parameters of glass and air are 1.5 and 1, respectively, that is, n 1 =1.5, n 0 =1. When light enters the glass from the air, it will be reflected on the surface of the glass. According to the Fresnel reflection law, 4% of the light will be reflected off. Similarly, when the light is shot from the glass into the air, it will also be reflected on the surface of the air. It produces 4% reflection, so regardless of the absorption of the glass itself, the highest transmittance of the glass is 92%.
