摘要：

A dielectric liquid lens is prepared based on our previous work. By optimizing the device structure, the liquid lens presents a converging focus with good resolution and changes its focal length over a broad range with a low driving voltage. For a liquid lens with similar to 2.3 mm diameter in the relaxed state, it can resolve similar to 40 lp/mm. The resolution does not degrade during focus change. Its focal length can be varied from similar to 12 to similar to 5 mm when the applied voltage is changed from 0 to 28 V-rms. The response time of one cycle is similar to 2.5 s. Our liquid lens, with a low driving voltage for a large dynamic range, has potential applications in imaging, biometrics, optoelectronic, and lab-on-chip devices.
