Abstract

A variable focus liquid lens is formed using two substrates with at least two through holes in at least one of the substrates. One end of each through hole is covered with a distensible membrane, one on the exterior surface of the substrate and the other on the interior surface. The substrates are sealed about the periphery to form a chamber and the chamber is filled with a liquid material. When pressure is applied to the membrane the liquid in the chamber is redistributed to form the lens. The variable focus liquid-filled lens is formed by providing a first and second substrate, forming at least two through holes in at least one of the first and second substrate, sealing one end of each of the at least two holes with a flexible transparent membrane, and sandwiching a liquid in a chamber formed between the first and second substrate.
