Abstract

The invention provides a processing method of a variable focus liquid microlens with controllable sensitivity. The method realizes the preparation of a chamber with an arc side wall by a liquid template technology, and is characterized by simpleness, high efficiency and low cost. The inner wall of the chamber of the prepared variable focus liquid microlens is smooth owing to the liquid template. Different curvature radii of the liquid template can be obtained by adjusting the wettability of a glass plate as the shape of the liquid has strong plasticity, thus realizing the adjustability and the controllability of the sensitivity of the variable focus liquid microlens.

Description

technical field [0001] The invention belongs to a processing method of a zoom liquid microlens with controllable sensitivity. Background technique [0002] As an important element of the optical system, the zoom lens has received more and more attention. Recently, with the development of optical communication technology and miniaturization technology, the demand for miniature zoom lenses is also increasing. Traditional zooming is usually achieved by combining lenses and adjusting the relative positions of the lenses by a mechanical device. This system is complex in structure, easy to wear and is not conducive to miniaturization. In order to achieve single-lens zoom and miniaturization, the prior art generally adopts a fluid zoom microlens based on electrowetting on a medium. The Chinese patent with the publication number CN 1705901 provides a function of adjusting the focal length of the microlens by using the principle of electrowetting. The controllable lens group inclu...
