Optical lens and method of manufacturing the same
First Claim
1. An optical lens comprising:
- a light-transmitting substrate which comprises a lens chamber and a fluidic chamber, wherein the lens chamber and the fluidic chamber are connected with each other;
a light-transmitting elastic film which seals the lens chamber;
a buffer elastic film which seals the fluidic chamber; and
an actuator on the buffer elastic film which corresponds to the fluidic chamber, and varies a volume of the fluidic chamber to vary a curvature of the light-transmitting elastic film.

Abstract
An optical lens is provided. The optical lens provides miniaturization and thin size, and reduces the cost and improves productivity by simplifying the structure and manufacturing process. The optical lens includes a light-transmitting substrate with a lens chamber and a fluidic chamber that are connected with each other. The optical lens also includes a light-transmitting elastic film which seals the lens chamber, a buffer elastic film which seals the fluidic chamber, and an actuator on the buffer elastic film which corresponds to the fluidic chamber, and varies the volume of the fluidic chamber to vary a pressure acting on the light-transmitting elastic film.
