Problems solved by technology

[0002] At present, lenses made of resin materials are generally used in the market, and the color filters required for various shootings are realized through dyeing. This kind of lenses has the following defects: 1. The resin substrate is molded and cannot meet the high surface precision requirements in the field of photography. , so it is usually impossible to focus when shooting; 2. The resin material substrate cannot withstand high temperature, so it is impossible to achieve various color films, waterproof films, and scratch-resistant films through vacuum optical coating, so during use , the surface of the resin sheet is easily scratched, dirty, and the service life is extremely short

Embodiment Construction

[0038] Such as Figure 1-Figure 2 As shown, the colored gradient dimming mirror of the present invention includes a glass lens 1 and a vacuum coating layer 2 coated on the glass lens 1, and the vacuum coating layer 2 includes Al with a thickness of 8.13nm from the inside to the outside. 2 o 3 The film layer 21, the Cr film layer 22 with a thickness of 55.29nm, the H with a thickness of 6.14nm 4 Film layer 23, the first layer of SiO with a thickness of 76.32nm 2 Film layer 24, a Ni film layer 25 with a thickness of 8.76nm, and a second layer of SiO with a thickness of 84.36nm 2 The film layer 26, the Fe film layer 27 with a thickness of 3.52 nm, and the SV-55 film layer 28 with a thickness of 87.80 nm. Of course, the thickness of each film layer is the optimal thickness in this embodiment, and each film layer can also be set to other thicknesses according to actual usage needs. Wherein, the SV-55 film layer 28 adopts SiO 2 and Al 2 o 3 The composition of the mixture is p...

Abstract

The invention relates to a colored gradient light-reducing mirror and a method of manufacturing the same. The colored gradient light-reducing mirror comprises a glass lens and a vacuum film plating layer plated on the glass lens. The vacuum film plating layer consists of a Al2O3 film layer, a Cr film layer, a H4 film layer, a first SiO2 film layer, a Ni film layer, a second SiO2 film layer, a Fe film layer and an SV-55 film layer successively from inside to outside. The mirror is made of a glass material and a light-reducing gradient colored filter lens is plated by using an optical vacuum film plating method, so that a problem of low surface precision caused by resin substrate forming is solved. The shooting becomes easy and the picture becomes clear and vivid, so that a light reducing-gradient colored filter lens is realized. Moreover, a problem that the surface is easy to scratch because the resin material is not resistant to the high-temperature vacuum optical film plating is solved; and thus the service life of the mirror is prolonged.
