We report an electro-wetting liquid lens with dual apertures which consists of internal channel with two variable interfaces and external channel with a plano-concave solid lens. And we use LC cell and Polarizers to achieve switching between internal and external channel. The proposed lens can achieve a large turning range of focal length, and the shortest positive and negative focal length are ~24 mm and ~−16 mm, respectively. Meanwhile, the experimental results show that the angular resolution of the proposed lens can reach to $\sim 29^{\prime \prime }$ . It has potential to be applied in cameras, microscopes and so on.

双孔径电润湿液体透镜

我们报告了一种具有双孔径的电润湿液体透镜,它由具有两个可变界面的内部通道和具有平凹固体透镜的外部通道组成。并且我们使用LC cell和Polarizers来实现内部和外部通道之间的切换。所提出的镜头可以实现较大的焦距转动范围,最短的正负焦距分别为~24 mm和~-16 mm。同时,实验结果表明,所提出的镜头的角分辨率可以达到 $\sim 29^{\prime \prime }$ . 它具有应用于照相机、显微镜等方面的潜力。
