Abstract

A kind of coloured gradual change dim light mirror, including glass lens and the vacuum coating that is plated on glass lens, the vacuum coating include Al successively outward by interior₂O₃Film layer, Cr film layers, H₄Film layer, first layer SiO₂Film layer, Ni film layers, second layer SiO₂55 film layer of film layer, Fe film layers and SV.The utility model uses glass material, and it is coated with dim light gradual change color filter using the method for optical vacuum plated film, solve the problems, such as that resin substrate is molded and existing face precision is inadequate, shooting is more easily enjoyed, picture becomes apparent from true to nature, it is truly realized dim light+gradual change color filter, and the utility model is efficiently solved because resin material is unable to the problem of surface caused by high temperature resistant vacuum optical coating easily scratches, and greatly improves product service life.

Description

A kind of coloured gradual change dim light mirror

Technical field

Photographic goods technical field is the utility model is related to, is specifically related to a kind of coloured gradual change dim light mirror.

Background technology

At present, the eyeglass of resin material is generally used on the market, is the color realized by dyeing needed for various shootings Filter, there are following defect for this eyeglass：1st, resin substrate, which forms out, does not reach the high face required precision of photography, so Situation about can not focus usually occurs during shooting；2nd, resin material substrate can not bear high temperature, so can not pass through vacuum light Plated film is learned to realize that various colour films, waterproof membrane, preventing from scraping film are coated with, so in use, resin sheet surface is easy to With regard to producing cut, dirty, service life is extremely short.

The content of the invention

The purpose of this utility model is that there are problem and shortage for above-mentioned, there is provided a kind of structure is reliable, service life It is long, the picture of acquisition can be made to become apparent from coloured gradual change dim light mirror true to nature.

What the technical solution of the utility model was realized in：

Coloured gradual change dim light mirror described in the utility model, its main feature is that：Including glass lens and it is plated on glass lens Vacuum coating, the vacuum coating includes Al successively outward by interior₂O₃Film layer, Cr film layers, H₄Film layer, first layer SiO₂ Film layer, Ni film layers, second layer SiO₂Film layer, Fe film layers and SV-55 film layers.

Wherein, the Al₂O₃The thickness of film layer is 8.13nm.

The thickness of the Cr film layers is 55.29nm.

The H₄The thickness of film layer is 6.14nm.

The first layer SiO₂The thickness of film layer is 76.32nm.

The thickness of the Ni film layers is 8.76nm.

The second layer SiO₂The thickness of film layer is 84.36nm.

The thickness of the Fe film layers is 3.52nm.

The thickness of the SV-55 film layers is 87.80nm.

The utility model compared with prior art, has following remarkable advantage：

1st, the utility model uses glass material first, and is coated with dim light gradual change coloured silk using the method for optical vacuum plated film Color filter, solves the problems, such as resin substrate shaping and existing face precision is inadequate, and shooting is more easily enjoyed, and picture is more clear It is clear true to nature；Moreover, realizing dim light gradual change color filter with glass material plated film first, filled up for color filter photography demander This market vacancy；

2nd, the utility model is efficiently solved because resin material is unable to table caused by high temperature resistant vacuum optical coating The problem of face easily scratches, greatly improves product service life；

3rd, the utility model not only can ensure that accurate color filter plated film, but can be needed for the accurate control product printing opacity Rate, is truly realized dim light+gradual change color filter.And traditional dyeing resin filter, realized by traditional dyeing colored Filter function, but because of technological problems, it is impossible to the light transmittance of eyeglass is controlled, simply simple coloring.

The utility model will be further described below with reference to the accompanying drawings.
