Paper Abstract

With the purpose of designing a variable-focal lens with large optical aperture, a liquid lens with liquid-membrane-liquid structure and 30mm optical aperture is proposed. Function of the inserted membrane is stated that much stronger elastic force takes place of interface tension, and enlarging aperture size of liquid lens becomes possible. Mechanics analysis of membrane’s deformation and finite element simulation was employed to demonstrate the elastic force maintains the deformation into a parabolic shape. Moreover, a prototype lens was designed and optical performance with a refractive power range of 7.7Diopters, and 7.13line-pair/mm resolution was measured in experiments.
