In this paper, a technique for the fabrication of a PDMS optical lens with the aid of a high electric field was introduced. The lens was fabricated by casting liquid PDMS onto a concave resin master formed under the repulsion between the negatively charged air-resin interface and the overhead high electric field. The focal length and surface profile of the lens under different electric fields were numerically simulated and experimentally verified. It was found that the profile of the air-resin interface can be quickly tuned by the applied electric field within 1 min. The surface roughness of the fabricated lens is about 2.15 nm. The magnification of the lens increases with the increase in the applied voltage and the decrease in the radius of the resin container. A lens with a radius of 3.0 mm and a magnification of 33.55 times was fabricated by applying a voltage of 6 kV.

在本文中，介绍了一种借助高电场制造 PDMS 光学透镜的技术。透镜是通过将液体 PDMS 浇铸到凹形树脂母版上而制成的，该母版是在带负电的空气-树脂界面和高架高电场之间的排斥力下形成的。对透镜在不同电场下的焦距和表面形貌进行了数值模拟和实验验证。结果发现，空气-树脂界面的轮廓可以在 1 分钟内通过施加的电场快速调整。制造的透镜的表面粗糙度约为2.15 nm。透镜的放大倍率随着施加电压的增加和树脂容器半径的减小而增加。一个半径为 3.0 毫米、放大倍数为 33 的镜头。
