Abstract

A fluidic lens device capable of providing variable focal power with reduced optical aberration is disclosed. The device includes a lens member and an actuator. The lens member comprises one or more elastic optical surfaces, a support member in communication with the optical surfaces, and a fluid-filled chamber. The optical surfaces have a high value of elastic modulus, reducing coma and other aberrations associated gravity and acceleration. The support member may provide a compliant fluid seal and allow the edges of the optical surfaces to pivot, reducing spherical and other aberrations. One or more piezoelectric ring-bender actuators may provide the force required for compressing the support ring and deflecting the optical surfaces. The actuators may be configured to provide the fluidic lens device with reduced sensitivity to changes in temperature.
