Patent ID: 8111466

Claim:
A method of focusing a liquid lens comprising: providing a microlens package having opposing major surfaces; providing a first fluidic channel within the microlens package, the first fluidic channel defining an inner surface of the microlens package; providing an opening through one of the major surfaces and a portion of the inner surface of the microlens package, the opening having a fixed circumference defining a first lens aperture which is in liquid communication with the first fluidic channel, the first fluidic channel containing a first lens fluid having sufficient surface tension to form a first liquid lens with a lens circumference in the opening; providing a first electrically controlled actuator integrated into the microlens package, wherein the first electrically controlled actuator is in communication with the first fluidic channel; and applying an electrical bias to the first electrically controlled actuator to control the flow of the first lens fluid along a direction of the first fluidic channel to actuate the first liquid lens in the first lens aperture, wherein the first liquid lens defines an air-liquid interface.
