Abstract
- 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.
