A remote control liquid continuous zoom lens

Abstract

The invention discloses a remote-controlled liquid continuous zoom lens, which is composed of a zoom assembly, a hollow rubber tube and a control assembly; The inner casing and the lower outer casing are connected. The outside of the inner casing is stepped. A sealing ring is provided between the lower step of the inner casing and the outer casing. The transparent elastic film is sleeved on the lower end of the inner casing and sealed by The ring is pressed tightly, and a chamber is formed between the transparent elastic film, the outer casing and the lower cover, and the chamber is filled with liquid. The lower sides of the outer casing are respectively provided with vent holes and liquid inlet nozzles that communicate with the inner chamber of the outer casing. , the liquid inlet nozzle is sealed by a sealing screw; the outer end of the liquid inlet nozzle is connected with one end of the hollow rubber tube, and the other end of the hollow rubber tube is connected with the control component. The invention is capable of remote control and continuous zooming, and has the characteristics of small size, light weight, fast response speed and excellent imaging quality.

Description

technical field [0001] The invention belongs to the field of micro-optics technology, and relates to a liquid zoom lens, in particular to a remote-controlled liquid continuous zoom lens. Background technique [0002] The lens is the soul of the camera module. Traditional lenses use glass or plastic as the base material, and undergo aberration correction to meet the needs of imaging. In many cases, such as shortening the distance between the scene and the camera when taking pictures, watching microbes with different scales when microscopic, the need for the focus point of the camera to be far and near, more detailed monitoring or expanding the monitoring range, and telescopes when observing objects with different distances Changing the magnification, etc., requires the focal length of the lens to change, that is, the zoom lens. A traditional zoom lens generally uses several lenses to form a lens group, and then a zoom lens is composed of 2 to 4 lens groups, and zooming is re...

AI Technical Summary

Problems solved by technology

The mechanically driven single liquid lens uses mechanical external force to squeeze or pump the liquid to change the volume of the liquid cavity containing the elastic transparent film, so that the elastic transparent film is raised or depressed to change the focal length of the lens; the mechanically driven single liquid lens The lens structure is complex, and the control accuracy and reliability are greatly limited

The electrowetting double-liquid lens uses the electric capillary phenomenon to drive the contact surface of two immiscible liquids with an applied voltage to change the contact angle between the two liquids and the hydrophobic insulating layer arranged between the two liquids, so that The curvature of the liquid surface changes to achieve zooming; this kind of liquid zoom lens is complicated to manufacture, the process is difficult, and the driving voltage is relatively large, which has exceeded the human body safety voltage of 36V
