VARIABLE VOLUME LIQUID LENSES

Abstract:

A liquid lens can include a chamber with first and second fluids and an interface between the fluids. A first electrode can be insulated from the fluids, and a second electrode can be in electrical communication with the first fluid. A position of the interface can be based at least in part on a voltage applied between the first and second electrodes. A flexure can be configured to cause a window to displace axially along an optical axis to change a volume of the chamber. The flexure can extend laterally outward from the window substantially linearly, and can be formed between a first recess on an outer side of the liquid lens and a second recess on an inner side of the liquid lens. The second recess can extend laterally outward farther than the first recess such that the first recess and the second recess are offset from each other.
