Abstract
A novel double liquid lens based on Electrowetting-On-Dielectric (EWOD) is presented and analyzed. The special construction is that the lens was divided into four quadrants. The particular fabrication process is presented to achieve the structure. It was proved that the lens not only expressed the electric zoom character but also shifted focal point away from optical axis. It also achieved an infinite focal length under zero electric field. The paper presented the relationship between the focus length and applied voltage, also gave the association between focus length and the applied voltage from 0V to 80V. We analyzed how the optical axis shifted according to the voltage difference between quadrants, furthermore, explained the new function that the focus object was away from center of lens.
