  • Method for manufacturing adjustable lens
    Patent number: 8883019
    Abstract: 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.
    Type: Grant

  • Optical power switch (OPS)
    Patent number: 8724198
    Abstract: The present invention is generally related to the field of optical systems and/or lens attachments, and more specific to an optical system and/or lens attachment providing a switchable Optical Power Switch (OPS) controllably switchable between different states. A soft transparent material (12), for example silicone-gel is disposed onto a surface of a glass plate (10). The glass plate (10) can be moved with actuators towards a surface of a lens body (10). When the soft material element (12) is in contact with the surface of the lens body (12), this surface changes its optical feature.

  • Flexible lens assembly with variable focal length
    Patent number: 8390939
    Abstract: The present invention is related to a lens assembly comprising a flexible lens body (10) inside a cavity bounded by a sidewall (11) and a first transparent cover (13), and a second transparent cover (14), wherein both covers (13,14) are in contact with respective surfaces of the lens body (10). Piezo electric elements (12) shapes the lens body (10) when activated, thereby adjusting the focal length of the lens assembly.

  • Method and arrangement for reducing thermal effects in compact adjustable optical lenses
    Patent number: 8310772
    Abstract: The present invention provides thermal compensation for a lens assembly comprising a polymer lens body. Polymers do have different thermal expansion coefficients which makes it necessary to compensate for thermal expansions to keep optical characteristics of such lenses within specifications when used under different environmental conditions. Also, it is necessary to provide thermal compensation during manufacturing of such lenses due to high temperatures during manufacturing steps.
