Abstract

The invention discloses an ultrathin liquid film zoom lens based on a liquid surface tension effect, and belongs to the technical field of optical lenses. The zoom lens is mainly composed of a front lens, flat glass and a rear lens. The front lens comprises a front lens cavity, a front liquid injection controller, a front liquid channel and a front liquid. The rear lens comprises a rear lens cavity, a rear liquid injection controller, a rear liquid channel and a rear liquid. By controlling the volume of the front liquid in the front lens cavity, the front liquid surface deformation in the front lens is realized by utilizing the surface tension effect of the front liquid. By controlling the volume of the rear liquid in the rear lens cavity, the rear liquid surface deformation in the rear lens is realized by utilizing the surface tension of the rear liquid. The liquid surface deformation in the front lens and the rear lens is controlled by controlling the liquid surface deformation in the front lens cavity and the rear lens cavity, and the zoom of the liquid film lens is realized by controlling the combination of the liquid surface deformation of the front lens and the rear lens. Thezoom lens has the advantages of being small in size, light in weight, low in cost, high in zoom speed, high in zoom precision and the like.

Description

technical field [0001] The invention relates to an ultra-thin liquid film zoom lens based on the effect of liquid surface tension, belonging to the technical field of optical lenses. Background technique [0002] The traditional solid material optical system adopts the method of changing the lens distance to achieve zooming, but this zooming method requires a cam mechanism to control the zooming track, which is relatively complicated to realize, and has a large volume and weight. error. At the same time, due to the limitations of the processing technology and zooming implementation method of the liquid zoom lens, the lens cavity still needs to retain a certain thickness to meet the processing and zooming requirements. Therefore, it is difficult to further reduce the lens volume by using a liquid lens. At the same time, the manufacturing process of the liquid lens is usually complicated and the cost is high. Contents of the invention [0003] In order to overcome the sho...
