Hybrid tunable lens for eliminating optical aberration and enlarging optical power

Abstract

In this paper, we propose a hybrid tunable lens based on electrowetting effect for eliminating optical aberration. By integrating a doublet lens in the front surface of a tunable lens, the proposed lens can achieve good image quality and obtain high optical power. Experimental results demonstrate that both two advantages can be achieved for the hybrid tunable lens. It can also reduce the operating voltage by ∼5 V to reach the same focal length, and it has compact structure, light weight, and good image quality.
