Fluidic lens with manually-adjustable focus
Abstract:
A fluidic lens may have a transparent window member, a transparent distensible membrane, an inner ring between the window member and membrane, and a top ring disposed such that the membrane is between the piston ring and the inner ring. A layer of liquid may be stored between the window member, the inner ring and the membrane. The top ring may be adapted to apply a liquid displacement force to the membrane in a direction perpendicular to a plane of an aperture of the inner ring to cause a change in a radius of curvature of the membrane. The membrane may be pre-tensioned prior to assembly with the other components.
