Double-sided anti-reflection film lens coating processing technology

The invention relates to the field of anti-reflection film lens processing, and discloses a double-sided anti-reflection film lens coating processing technology particularly for a non-planar lens. Thetechnology adopts a creative spin coating technology, a Sol-Gel principle is utilized for making, the thickness of a coating layer is controlled through the spin speed, the turning time, the solventevaporation speed and the lens position to meet the needed optical performance requirements, the shorter the spinning time is, the smaller the thickness of the coating layer is, and the longer the turning time is, the smaller the coating layer thickness is; and the higher the solvent evaporation speed is, the thicker the coating layer is. According to the double-sided anti-reflection film lens coating processing technology, for the broadband wavelength from 400 nm to 800 nm, anti-reflection films with the high performance and the anti-reflection performance can be obtained; when the inclination angle (CRA) and the inci
