Abstract
A liquid lens can have a chamber configured to improve the performance of the liquid lens, such as by improving the tilt response time and/or by reducing optical aberrations. The chamber can have sidewalls that conform to a shape of a truncated cone. The cone angle, and wide end diameter, and narrow end diameter can be selected by balancing competing factors. The liquid lens can include two fluids, and the fluid fill ratio can be selected to improve the performance of the liquid lens. In some embodiments, the sidewalls can conform to a portion of a sphere.
