The present invention provides method steps for manufacturing an assembly of adjustable lenses on a wafer. The method steps provide an easy manufacturing of such lenses, minimizing the cost of assembly, and at the same time provide a solution for mass production of compact adjustable lenses for use in mobile phones, etc.

Method for manufacturing adjustable lens

The present invention is related to a lens assembly comprising a flexible lens body () inside a cavity bounded by a sidewall () and a first transparent cover (), and a second transparent cover (), wherein both covers () are in contact with respective surfaces of the lens body (). Piezo electric elements () shapes the lens body () when activated, thereby adjusting the focal length of the lens assembly.

Flexible lens assembly with variable focal length

The present invention provides a solution for designing a compact adjustable lens assembly, wherein a circular shaped piezoelectric crystal is bending a thin glass cover, thereby providing a shift of focal length of the lens assembly.
