Abstract

A fluidic lens may have a reservoir at least partially bounded by a first optical surface and a second optical surface. A fluid fills a volume of the reservoir. A piston is configured to contact a portion of the first or second optical surface from outside the reservoir. One or more of the first optical surface or second optical surface is configured to deform as a result of a change in a pressure applied to the fluid or a change in contact between the piston and the first or second optical surface. A rim is configured to contact a portion of the first or second optical surface from outside the reservoir. One or more of the first optical surface or second optical surface is configured to deform as a result of a change in a pressure applied to the fluid or a change in contact between the rim and the first or second optical surface.
