The invention relates to a coated lens, in particular to a high-hardness anti-reflection coated lens applied to the fields of automobile rearview mirror, motion cameras, VR/AR and the like.
The background technology is as follows:
The existing lens applied to the fields of automobile rearview mirror, moving camera, VR/AR and the like generally uses a film structure formed by oxide materials ZR lanthanum titanate, TI series materials, SI series materials, MGF2 and the like, and the defects of sparse film compactness, low hardness and easiness in scratching or grinding in the use process generally exist.
The invention comprises the following steps:
In order to solve the problems that the existing lens is sparse in film compactness and low in hardness and is easy to scratch or abrade in the use process, the embodiment of the invention provides a high-hardness anti-reflection coated lens.
The high-hardness anti-reflection coating lens comprises a glass substrate, wherein the upper surface of the glass substrate is sequentially provided with: a first Si film, a first Nb 2O5 film, a second Si film, a second Nb 2O5 film, a third Si film, a third Nb 2O5 film, and a surface Si film.
According to the embodiment of the invention, the first Si film layer, the first Nb 2O5 film layer, the second Si film layer, the second Nb 2O5 film layer, the third Si film layer and the third Nb 2O5 film layer are arranged on the glass substrate to jointly form the functional layer, so that the effect of improving the compactness and hardness of the film layer is achieved; the surface Si film layer has the functions of reducing the reflectivity, improving the hardness, and the like. Can effectively prevent the lens from being scratched or abraded in the using process.
Description of the drawings:
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required for the description of the embodiments will be briefly described below, and it is apparent that the drawings in the following description are only some embodiments of the present invention, and other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
