Description
Technical Field
The invention relates to the field of optics, in particular to a lens-increasing sheet convenient to repair and a preparation method thereof.
Background
When light is perpendicularly incident on a common glass surface, the ratio (reflectivity) of the intensity of the reflected light from the incident surface to the intensity of the incident light is only determined by the ratio of the refractive indexes of adjacent media, namely about 4.2% of the crown glass with the refractive index of 1.52 is reflected from each surface. The higher refractive index flint glass is more pronounced in surface reflection. This surface reflection has two serious consequences, namely, the loss of light energy reduces the brightness of the image, and the reflected light on the surface is reflected or diffused repeatedly, and part of the reflected light becomes stray light and finally reaches the image plane to reduce the contrast of the image, and especially, complex systems such as televisions, cinematographic lenses and the like all comprise a plurality of surfaces adjacent to air, and the performance of the complex systems is greatly reduced if the complex systems are not plated with an antireflection film, so that the instruments are plated with an antireflection film on the surfaces.
The optical instruments applied to the visible spectrum are very many, and occupy most of the antireflection film in terms of the yield, and antireflection treatment is performed on almost all optical devices. Particularly, the surface of the lens of the visible vision optical lens is generally plated with a visible width antireflection film so as to improve the light flux of the lens and reduce the image quality problems such as ghost images.
The film plating process generally adopts PVD (physical vapor deposition) technology, and although the existing film plating equipment and technology are mature, the film thickness control precision is nano-scale, and the anti-reflection film has the performance requirements of smoothness, firmness and the like besides the spectral reflectivity index requirement. Therefore, if the coating index is not qualified or other performance indexes are not qualified, the lens can be scrapped, because the film layer deposited on the surface of the lens is difficult to completely remove, the film layer cannot be removed by a chemical method, the film color can be influenced by the residual uneven film layer, the color spots and other anomalies can occur, and the problems of high lens and the like can be caused by excessive removal of the lens base material by a physical re-polishing method. The repair cost is high and the yield is low.
Disclosure of Invention
The invention provides a lens-increasing sheet convenient to repair and a preparation method thereof, and the lens-increasing sheet convenient to repair can remove a film layer plated on a lens cleanly when a film coating index is unqualified or other performance indexes are unqualified, and can not weaken an antireflection effect after successful plating, so that the lens-increasing sheet convenient to repair has excellent antireflection effect in a visible light range.
The invention is realized by the following technical scheme:

A preparation method of an anti-reflection lens convenient to repair comprises the following steps of cleaning a lens substrate, plating a silver layer with a thickness of 2-4 nm on the outer side surface of the lens substrate, and plating the anti-reflection film layer on the outer side surface of the silver layer.
