Abstract
A liquid lens structure with a step response time of 2 ms, a refractive power range of 52 D, and a root-meansquare (RMS) wavefront error of 80.3 nm is reported. This lens uses a liquid-liquid interface with a pinned contact line as a variable refractive surface, and its shape is controlled by a piezo stack actuator via a built-in hydraulic amplifier. The potential applications of this device include axial focus scanning of microscopes and focusing/zooming of camera lenses and machine vision systems.
