Abstract

Adaptive elastomer-liquid lens can find a variety of optical applications due to the tunable optical powers without additional lens replacement or displacement. Most current elastomer-liquid lenses use elastomer membrane with a constant thickness. This approach, however, suffers from substantial optical aberration due to the edge clamping effect. In this study, a varied thickness elastomer membrane with customized aspherical profile is designed and developed to encapsulate a plano-convex liquid lens. Such varied thickness membrane is fabricated by double-side replica molding against a deformed elastomer-liquid lens membrane with a constant thickness. Such configuration could alleviate the edge clamping effect. Simulation and experimental results both show that the lens with a varied thickness membrane exhibits improved optical resolutions at both the center and the peripheral regions at the back focal length of 10 mm comparing to the lens with a constant thickness membrane. This study provides an effective solution to suppress the optical aberrations without sacrifice of the optical aperture.
