Problems solved by technology

However, most of the flexible zoom lenses in the prior art need to be fixed by the frame as a whole. For example, they can only be used in full-frame glasses, which do not meet the aesthetic requirements of consumers, and the installation and processing are complicated, which cannot meet the increasing needs of people.

Abstract

The embodiment of the invention relates to a lens system. The lens system comprises a substrate, an attached piece, transparent fluid and a pressure adjustor; the substrate and the attached piece arelenses with focal power and of gradational non-spherical shapes; and the attached piece can produce corresponding shape change along the change of the borne pressure; the substrate and the attached piece are connected by adopting a splicing way of hot-melting or optical gluing, or integrated and connected by adopting a molding in one technology; an enclosed cavity is formed between the substrate and the attached piece so as to adjust the volume of the transparent fluid; the pressure adjustor enables the volume of the transparent fluid in the enclosed cavity to change by changing the filling pressure of the transparent fluid, thereby enabling various surfaces of the lens system to deform; the optical characteristic is presented that the entire focal length is changed, and the zooming is realized; the lens system disclosed by the embodiment of the invention can be suitable for various optical instrument equipment so as to realize the zooming, the variation and like optical functions; theinstrument is small in volume, high in performance and low in cost.

Description

technical field [0001] The invention relates to the technical field of optical devices, in particular to a lens system. Background technique [0002] Traditional zoom optical lens systems are usually composed of several optical components (lenses) with fixed focal lengths, relying on the forward and backward movement of the components to adjust the focal length of the system, or to achieve bifocal and progressive zoom on one lens, such as bifocal and progressive type lenses. [0003] The lens system composed of several optical components (lenses) has high requirements on the precision of mechanical positioning and moving parts. The entire zoom system has complex structure, high energy consumption of the drive system, large volume and weight, and high manufacturing cost. [0004] For example, the lenses of bifocal glasses are composed of upper and lower lenses with different focal lengths. The upper half is suitable for seeing far away, and the lower half is suitable for see...
