Fluid-Filled Tunable Lens

A tunable lens having a periphery, the tunable lens comprising:

• a lens element;
• a ring-shaped chassis that extends around the periphery;
• bladders positioned along the periphery between the ring-shaped chassis and the lens element, wherein each bladder is configured to adjust a displacement between the ring-shaped chassis and the lens element at a respective position along the periphery;
• and
• actuators positioned on the ring-shaped chassis, wherein each actuator is adjacent to a respective bladder of the bladders and is configured to adjust an amount of fluid in its respective bladder.

A tunable lens comprising:

• a lens element that forms part of a fluid-filled chamber;
• one or more actuators configured to change a shape of the lens element;
• and
• a fluid-controlling component that is configured to adjust an amount of fluid in the fluid-filled chamber, wherein the fluid-controlling component comprises:
• a flexible bladder with ribs that is aligned with an inlet for the fluid-filled chamber, wherein the flexible bladder has a volume that is configured to contain fluid;
• and
• a scissor jack portion that is attached to the flexible bladder, wherein the scissor jack portion is configured to extend in a given direction to shrink the volume of the flexible bladder and push the fluid from the flexible bladder into the fluid-filled chamber.

A tunable lens having a periphery, the tunable lens comprising:

• a lens element;
• a chassis having a ring-shaped portion that extends around the periphery and an additional portion, wherein the ring-shaped portion of the chassis comprises fluid channels;
• bladders positioned along the periphery between the ring-shaped portion of the chassis and the lens element, wherein each bladder is configured to adjust a displacement between the ring-shaped portion of the chassis and the lens element at a respective position along the periphery;
• and
• fluid-controlling components at the additional portion of the chassis, wherein each fluid channel of the fluid channels is interposed between a respective bladder of the bladders and a respective fluid-controlling component of the fluid-controlling components.
