Smooth Metal Electrowetting Lens Cavity and Lens System

An electrowetting lens comprising:

• a housing;
• an electrowetting lens cavity disposed within an upper portion of the housing, the electrowetting lens cavity comprising a metal chamber with an inner surface tapering downward to form an aperture;
• wherein the inner surface of the electrowetting lens cavity is smooth enough to allow electrowetting lensing within the electrowetting lens;
• an electrode and an electrode ground disposed for providing potential between a wall of the electrowetting lens cavity and above the electrowetting lens cavity;
• a top window;
• and
• a bottom window.

The method of forming an electrowetting lens comprising the steps of:

• providing a housing;
• providing an electrowetting lens cavity sized and shaped to fit within the housing;
• providing top and bottom windows;
• and
• providing means to apply a voltage between the electrowetting lens cavity and the top of the housing;
• wherein the electrowetting lens cavity is formed of a metal chamber with an inner surface tapering downward to form an aperture and the inner surface of the electrowetting lens cavity is smooth enough to allow electrowetting lensing within the electrowetting lens.
