Abstract

The invention discloses an asymmetric liquid lens, a manufacturing method thereof, an optical device and equipment. The manufacturing method of the asymmetric liquid lens comprises the following steps: arranging an interdigital electrode on the surface of a substrate; coating the surface of the substrate with an insulating film, and covering the interdigital electrode; arranging a limiting piece on the side, provided with the interdigital electrode, of the substrate to form a containing cavity; injecting first dielectric liquid and second dielectric liquid into the containing cavity to form a refracting surface; and adjusting the curvature of the refracting surface through the electromagnetic field of the interdigital electrode, and obtaining the asymmetric liquid lens. According to the asymmetric liquid lens, the size of the focal length of the lens is changed by changing the size of the access voltage of the interdigital electrode and adjusting the shape and the curvature radius of the refracting surface formed by the first dielectric liquid and the second dielectric liquid, so that the multi-scene application of the same asymmetric liquid lens is realized, and the universality is improved; in addition, the manufacturing method is easy to operate, and the prepared asymmetric liquid lens can have better surface performance.

Description

technical field [0001] The present application relates to the field of lenses, in particular to an asymmetric liquid lens and its manufacturing method, optical device and equipment. Background technique [0002] In the related art, the processing method of the lens is often mechanical processing. Since the focal length of the prepared lens is fixed, it cannot be applied to the use requirements of multiple scenarios, and the versatility is low. Contents of the invention [0003] This application aims to solve at least one of the technical problems existing in the prior art. For this reason, the present application proposes a method for manufacturing an asymmetric liquid lens, which can prepare an asymmetric liquid lens with a zoom function, can meet the use requirements of multiple scenarios, and improve versatility. [0004] The method for manufacturing an asymmetric liquid lens according to the embodiment of the first aspect of the present application is characterized in...
