Abstract: Double liquid lens based on electrowetting is a novel design of lenses. It can vary the focal length by changing the external voltage to focus and zoom without lens displacement. The history of this kind of lens and its principle is introduced, and the relationship of focal length and external voltage in two models are analyzed.
Key words: electrowetting, liquid lens, variable - focus
