Liquid lens

Abstract

The invention provides a zoom lens. According to the zoom lens, through an electrowetting reaction and / or an inverse piezoelectric effect of a conducting shell or a driving electrode, the diopter of aliquid surface is changed, it is convenient to make an optical zoom system small, the focusing range of the optical zoom system is expanded, the application scene of the optical zoom system is broadened, and the applicability of the optical zoom system is enhanced.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a liquid lens. Background technique [0002] At present, the optical system, especially the optical zoom system, is usually made of a solid lens with fixed focal length. In order to adjust its focal length, the optical zoom system needs to use multiple groups of solid lenses, and the movement of the solid lens is driven by mechanical parts to realize the focusing of the optical zoom system. Therefore, , there are problems that the optical zoom system has a complex structure, is not easy to miniaturize, is not convenient for precise control, and has relatively poor reliability. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a liquid lens for solving the problem of inconvenient miniaturization of the optical zoom system in the prior art. [0004] In order to achieve the above pu...
