Abstract: Electrowetting optical devices can comprise a first electrode at least partially circumscribing a first optical window and a second electrode at least partially circumscribing a second optical window. The second optical window may be aligned with the first optical window in a direction of the optical axis. A central region may be defined by a projection of a footprint of the second optical window. An interface between a first liquid and a second liquid that may be disposed within a containment region may form a lens. In some embodiments, a thickness of a second dielectric portion at least partially circumscribing the central region may be greater than a thickness of a thirst dielectric portion within the central region. In some embodiments, a capacitance per area of the device upon application of a maximum operating voltage may be in a range from about 0.1 pF/mm2 to about 3.5 pF/mm2.
