ABSTRACT:
A variable lens system includes a chamber with an optical axis extending through the chamber. The chamber contains a first fluid and a second fluid in contact over a meniscus extending transverse the optical axis. The perimeter of the meniscus is fixedly located on an internal surface of the chamber. The fluids are substantially immiscible and have different indices of refraction. A pump is arranged to controllably alter the shape of the meniscus by altering the relative volume of each of the fluids contained within the chamber.
