Abstract

The invention discloses a liquid continuous zooming lens which comprises a precession device, an upper cover plate and a lower cover plate, wherein the upper cover plate is positioned on the upper surface of the precession device, the lower cover plate is positioned on the lower surface of the precession device, and both the upper cover plate and the lower cover plate are made of transparent materials; and the precession device is formed by connecting an upper inner sleeve with a lower outer sleeve, an inner hole of the outer sleeve is a stepped hole with a large upper part and a small lower part, a transparent elastic film is arranged on the step of the stepped hole, a seal pressing ring is installed on the inner side of the lower part of the outer sleeve, the transparent elastic film is tightly pressed on the outer sleeve by the seal pressing ring, a cavity is formed by the transparent elastic film, the outer sleeve and the lower cover plate, and liquid is filled in the cavity. The liquid continuous zooming lens has the advantages of simple structure, small size, light weight, stabilization of an optical axis, continuity in zooming, high response speed, high precision, convenience in operation and easiness in processing.

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 liquid continuous zoom lens. Background technique [0002] Traditional lenses are generally made of glass or plastic materials, and the aberrations are corrected by adjusting the radius, thickness, and aspheric parameters of the lens to meet certain requirements. However, with the further needs of science and technology, production and life, the traditional lens with a small zoom range and strict requirements on the drive motor is on the verge of the size limit that can be achieved, and cannot meet the needs of industrial development, and its application is greatly restricted. In order to realize the miniaturization of the zoom lens, some new zoom microlens technologies have been proposed at home and abroad, and the liquid zoom lens is one of them. The liquid lens is made of liquid, which imitates the focusing principle of the human eye...
