Abstract

The invention provides a waterproof anti-reflection film, a lens and an imaging device. The waterproof anti-reflection film comprises: a base layer; a waterproof layer which is connected to at least one side surface of the base layer; and an anti-reflection layer which is arranged on the surface of the side, away from the base layer, of the waterproof layer, wherein the anti-reflection layer comprises a plurality of first film layers and a plurality of second film layers which are different in refractive index, and when the number of the first film layers and the number of the second film layers are multiple, the first film layers and the second film layers are alternately stacked. The problem that an anti-reflection film in the prior art is poor in waterproof effect is solved.

Description

technical field [0001] The invention relates to the technical field of optical imaging equipment, in particular to a waterproof anti-reflection film, a lens and an imaging device. Background technique [0002] Optical resin materials have gradually replaced optical glass in the field of mobile phone optical lenses due to the advantages of light weight, small dispersion, and easy molding and processing. For example, PMMA, COC, COP and other polymer materials. However, the shortcomings of optical plastics such as moisture resistance, large expansion coefficient, and poor dimensional stability limit their application in large-curvature optical lenses. Because in the high temperature and high humidity reliability test, the optical resin lens has a certain degree of water absorption, so the resin lens in the lens will have a certain degree of surface change, and the surface change will cause the imaging system to be defective. Moreover, at present, the anti-reflection film of t...
