Abstract: A method, a user interface and a system for use in determining shade of a patient's tooth, wherein a digital 3D representation includes shape data and texture data for the tooth is obtained. A tooth shade value for at least one point on the tooth is determined based on the texture data of the corresponding point of the digital 3D representation and on known texture values of one or more reference tooth shade values.

Abstract: The present invention relates to transparent optical device elements comprising a deformable lens body and to a method for changing the refractive index (RI) of a deformable lens body. The deformable lens body of the invention has an improved mechanical stability, a high refractive index, an optimal degree of stiffness and sheer modulus for use as optical lens.

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.

Abstract: The present invention relates to a row of lids (1) defining an unbroken sheet material having a longitudinal direction, the sheet material being shaped so that the rim of the sheet material defines first rims section (3) of the lids (2) and so that second rims sections (4) of two lids (2) being adjacent to each other in the row of lids are defined by one cut in a direction being different from perpendicular to the longitudinal direction (5) of the sheet material.

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.

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.

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.
