Lens focusing mechanism

Abstract

The invention provides a lens focusing mechanism comprising an elastic lens surface, a liquid storage chamber, a connecting pipe and a permeable membrane, wherein an accommodating chamber is defined in the elastic lens surface, and at least two liquids which are not mutually dissolved and have different refractive indexes are in the accommodating chamber; the liquid storage chamber is disposed onthe outer side of the elastic lens surface and communicated with the accommodating chamber; one end of the connecting pipe is communicated with the liquid storage chamber, and the other end of the connecting pipe is communicated with the accommodating chamber; and the permeable membrane is arranged between the connecting pipe and the accommodating chamber. According to the lens focusing mechanism,by utilizing the structure of combining the elastic lens surface, the liquid storage chamber, the connecting pipe and the permeable membrane, flexible focusing can be achieved, and the lens focusingmechanism has the advantages of having a wide focusing range, being convenient to use and facilitating processing and production.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a lens focusing system. Background technique [0002] Existing zoom lenses are mainly used in optical lenses such as photography and photography.
