Problems solved by technology

The main material of the optical film is inorganic material, but due to the difference in the physical and chemical properties of the polymer resin lens substrate and the inorganic material film layer, the stress of the finished lens is high, resulting in poor temperature and environment resistance, especially anti-reflection and anti-near Infrared laser has a thick film layer, which has a particularly significant impact; in addition, due to the poor temperature resistance of the lens material itself, it has a better use effect

Abstract

The invention provides an anti-reflection and near-infrared laser prevention resin lens. The anti-reflection and near-infrared laser prevention resin lens comprises a resin lens substrate, a hardening layer and an anti-reflection and near-infrared laser prevention film layer, wherein the substrate, the hardening layer and the anti-reflection near-infrared laser prevention layer are arranged in sequence, the hardening layer is located on the surface of the resin lens substrate, and the anti-reflection layer is located on the surface of the hardening layer; and the anti-reflection near-infrared laser prevention layer is mainly formed by alternately arranging a high-refractive-index material TiO2 layer, a special low-stress silicon boron oxide film layer of a low-refractive-index material layer and a transparent conductive material ITO (Indium Tin Oxide) layer. According to the invention, deeper cut-off (transmission is about 10% or lower) of several main near-infrared band lasers is realized, meanwhile, the temperature resistance and environment resistance of the resin lens for preparing glasses are improved, and the resin lens has good application and market prospects.

Description

technical field [0001] The invention relates to the technical field of resin lens preparation, in particular to a resin lens for anti-reflection and anti-near-infrared laser. Background technique [0002] In recent years, the demand for optical resin lenses in the domestic and foreign glasses markets has been increasing. Compared with glass lenses, resin lenses have the advantages of light weight, good dyeing performance, and easy processing. Medium and high refractive index optical resin lenses are more transparent High efficiency, UV protection, ultra-thin and other unique advantages are favored by users. [0003] Generally, in the lens industry, a lens with a refractive index above 1.60 is a high refractive index, a refractive index of 1.56 is a medium refractive index, and a refractive index below 1.56 is a low refractive index. There are many factors that affect the refractive index of the lens. Due to the structural difference of the lens material itself, its absorpti...
