Referring to fig. 1, fig. 1 is a schematic view of a multilayer film anti-reflection polarizing lens according to an embodiment of the utility model.
As shown, a multilayer film antireflective polarized lens comprising: a resin substrate 10, wherein a polarizing film 11 is sandwiched inside the resin substrate 10; a stiffening layer 20 dip-coated on the resin substrate 10; an ultraviolet light curing protective layer 30 spin-coated on the stiffening layer 20; the composite anti-reflection layer 40 plated on the ultraviolet light curing protective layer 30 comprises a porous silicon dioxide film 41, a magnesium oxide film 42, a metal oxide film with a refractive index greater than 2 and an aluminum oxide film 44.
In one embodiment of the present utility model, the polarizing film 11 is placed on a rubber ring, then glass molds on both sides are fixed, resin is filled in the rubber ring, and the resin substrate 10 is obtained after curing, and a polarizing lens is molded. The surface of the resin substrate 10 is dip-coated in a hardening liquid to form a hardening layer 20, which improves the surface hardness of the lens. The ultraviolet light curing protective layer 30 is spin-coated on the surface of the hardening layer 20 by a spin coater, and the surface of the lens is protected by ultraviolet light curing. The composite anti-reflection layer 40 is composed of a porous silica film 41, a magnesia film 42, a metal oxide film with a refractive index greater than 2, and an aluminum oxide film 44, wherein the porous silica film 41 can enhance the transmission of the lens and can be porous through ion erosion.
