电可调透镜提供了通过施加电场来控制焦距的可能性。已经展示了不同的液晶可调透镜。为了最大限度地减少透镜像差，多电极设计允许我们针对每个可能的焦距微调施加的电压。在这封信中，我们提供了一种新的多电极设计，其中只需要一个光刻步骤，因此与以前提出的设计相比，提供了一个大大简化的制造工艺。关键因素是使用高介电常数层，并结合浮动电极。(C)2018年美国光学学会
Electrically tunable lenses offer the possibility to control the focal distance by applying an electric field. Different liquid crystal tunable lenses have been demonstrated. In order to minimize lens aberrations, multi-electrode designs allow us to fine-tune the applied voltages for every possible focal distance. In this Letter, we provide a novel multi-electrode design in which only one lithography step is necessary, thereby offering a greatly simplified fabrication procedure compared to earlier proposed designs. The key factor is the use of a high-permittivity layer, in combination with floating electrodes. (c) 2018 Optical Society of America
