- Abstract
A kind of adjustable even aspheric liquid lens combined with electric wetting effect and electrostatic force is proposed. The aspheric liquid lens is simulated by using Comsol Multiphysics software. The electrostatic force generated by four circular electrodes can flexibly adjust the surface shape of the liquid lens. The zoom optical system is designed by using the liquid lens. The aspheric equation for optimizing and correcting the aberration is obtained by using the Zemax software. As the target surface of the adjustable even aspheric liquid lens, the voltage on the electrowetting electrode and the four-ring electrode is adjusted. The simulated root mean square error of the optical path between the aspheric surface and the target aspheric surface is less than λ /14, which meets the Marechal criterion. In the range of 26~30 mm focal length, compared with the aspheric liquid lens system with the ring electrode voltage of 0 V, the adjustable even aspheric liquid lens zoom system with the ring electrode voltage has good imaging effect.
