Remote-controlled continuous zoom lens with liquid

Abstract

The invention discloses a remote-controlled continuous zoom lens with liquid, comprising a zoom component, a hollow rubber tube and a control component, wherein the zoom component comprises a main body, an upper cover plate arranged on the main body, and a lower cover plate arranged below the main body; the main body is formed by connecting an upper inner sleeve with a lower outer sleeve; the exterior of the inner sleeve is step-shaped, and a sealing ring is arranged between the step part at the lower part of the inner sleeve and the outer sleeve; a transparent elastic membrane is sheathed at the lower end surface of the inner sleeve and is pressed by the sealing ring; a chamber is formed among the transparent elastic membrane, the outer sleeve and the lower cover plate and is filled with the liquid; a vent and a liquid inlet mouth are respectively arranged at two sides of the lower part of the outer sleeve and are communicated with the chamber in the outer sleeve; the liquid inlet mouth is sealed by a sealing screw; and the external end part of the liquid inlet mouth 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 remote-controlled continuous zoom lens can realize remote control and continuous zooming, and has the advantages of small volume, light weight, high 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...

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
