Abstract
A liquid lens can include a chamber and a first fluid and a second fluid contained in the chamber. The first fluid and the second fluid may be immiscible, forming a fluid interface between the two fluids. The liquid lens may also include a first electrode insulated from the two fluids. The liquid lens may include a second electrode in electrical communication with the first fluid. The liquid lens may be configured such that a position of the fluid interface is based at least in part on voltages applied to the electrodes. The lens may further include a window configured to transmit light therethrough along an optical axis. Further, a flexible member may be configured to cause the window to displace axially along the optical axis to change the volume of the chamber.
