摘要： The present invention relates to a variable focus lens. The variable focus lens comprises a fluid chamber having a protrusion formed along one opened end thereof. The fluid chamber is cylindrically shaped to house first and second non-miscible fluids therein, and the first and second fluids have different refractive indices. A transparent element hermetically is coupled with the opened end of the chamber with a predetermined gap from the protrusion of the chamber. A first electrode is disposed inside the chamber to act on the first fluid, and a second electrode is insulated from the first electrode. The variable focus lens can be easily fabricated to prevent bubble formation with the protrusion formed at the opened end of the chamber.

摘要： The invention provides a variable focus liquid lens using electrowetting, comprising a conductive first liquid and an insulating second liquid. At least one of the first liquid composed of electrolyte and the second liquid composed of insulating liquid contains a surfactant for reducing interfacial energy between the first and second liquids. An interfacial portion between the first and second liquids is gathered by surfactant to reduce driving voltage. The variable focus liquid lens according to the invention has about 50% lower driving voltage required for changing focus, ensuring stability of the two fluids.
