Detailed Description
The invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The invention provides a coated lens with a mirror image layer. As shown in fig. 1 to 9, the novel film system is arranged on the surface of the lens substrate, and the novel film system can be well attached to the surface of the lens substrate, and meanwhile, double-sided high reflection is ensured, so that the two sides of the lens substrate respectively reflect light of different adjustable light domains without interference.
The novel film system comprises a multi-layer structure, wherein the middle of the novel film system is a nickel-chromium material mixed material layer, and the two sides of the mixed material layer can be designed to stack reflection layers with various colors, namely, high-refractive-index material layers and low-refractive-index material layers are alternately stacked. Through the absorption of the middle mixed material layer, the transmitted light is weakened, and the high reflection can be generated on both sides of the mixed material layer by controlling the optical film thickness of the high and low refractive index materials on both sides, the colors and the optical properties on both sides of the mixed material layer can be respectively adjusted, so that the product presents rich colors.
In the nickel-chromium material mixed material layer, the mixing proportion of nickel and chromium materials is 2.5-3.5:0.5-1.5, and the physical film thickness range of the layer is 100-400 nm. The principle of the design of the mixed material layer is as follows:
the nickel (Ni) neutral beam-splitting and absorbing layer has stable physical property in air, and the nickel coating is mainly characterized in that the nickel has strong passivation capability, and the surface can rapidly generate an extremely thin passivation film to isolate the nickel matrix from air, so that the nickel coating can resist the corrosion of atmosphere, alkali and certain acids. Meanwhile, in the simple salt plating solution of nickel, a plating layer with extremely fine crystals can be obtained, and the plating layer has good polishing performance.
The adhesion capability of metal chromium (Cr) is strong. Cr has very good mechanical strength and chemical stability, and also has very good neutrality, and the change of the spectral ratio with wavelength is very small, so that a chromium film is commonly used for a metal film neutral spectroscope. In the visible region, the beam of the chromium film split reflection light is white, and the beam of the transmission light is slightly brown.
Nickel and chromium are mixed in a ratio of 2.5-3.5:0.5-1.5 to form a mixed material layer, and a layer of chromium is added between the lens base material and the nickel, so that the adhesive force between the nickel and the lens base material is improved, and the mechanical stability of an interface is maintained. The film layer can well give consideration to the mechanical property and the optical property of the film layer.
Setting in the scheme L i An ith layer, R, representing one side of the nickel-chromium material mixed material layer i An i-th layer on the other side of the nickel-chromium material mixed material layer is represented, and C represents the nickel-chromium material mixed material layer. Wherein a larger value of i indicates that the layer is further from the nickel chromium material mixed material layer. The novel film system structure is as follows: l (L) N +......L 3 +L 2 +L 1 +C+R 1 +R 2 +R 3 +......R N 。
The method does not limit the number of the high refractive index material layers and the low refractive index material layers on two sides of the nickel-chromium material mixed material layer, and can freely select the corresponding number of the film layers according to production and processing requirements, wherein the film layers contacted with the lens base material are the low refractive index material layers.
