  • Patent number: 8052278
    Abstract: An optical component (10) comprises at least one transparent set of cells (15) juxtaposed parallel to a surface of the component, each cell having a size and a geometry that are different from those of its neighbors forming a network of cells with random distribution and random geometry, parallel to the surface of the component. Each cell is hermetically sealed and contains at least one substance with optical property. The invention also comprises a method of producing such an optical component and its use in the fabrication of an optical element. The optical element can in particular be a spectacle lens.

  • Patent number: 7938536
    Abstract: According to a process for manufacturing a series of ophthalmic lenses, each lens consists of a substrate and a film portion (3) attached to the substrate. The characteristics specific to each lens are obtained by functionalizing the film portion. Film functionalization is carried out when the film is in the form of a large planar sheet (2), and then each portion is cut from the sheet. To obtain economic lens manufacture, with a good production yield, the film portions have, right from the start of the process, dimensions corresponding substantially to the housing of a frame into which each lens is intended to be fitted.

  • Publication number: 20110043925
    Abstract: A transparent optical component comprises two sets of cells (1) disposed in respective superposed layers (10, 20). Each cell (1) contains an optically active material, and the cells in each set are isolated from one another by separating portions (2) within the corresponding layer. The cells (1) of one layer are offset relative to the cells of the other layer so as to be located in line with the separating portions (2) pertaining to the other layer. Such optical component exhibits transparency that is improved compared with components having a single layer of cells or cells that are superposed.

  • Patent number: 7891809
    Abstract: An optical component comprises a transparent network of cells juxtaposed and separated by walls parallel to a surface of the component, each cell being hermetically sealed and comprising at least one substance with an optical property, and all or part of the surface of said component comprises walls less than 100 nm thick. The optical component is thus pixelized by a cell network, the cells being separated by walls which may themselves be pixelized. Such an optical component is particularly useful for making optical elements such as ophthalmic lenses.

  • Publication number: 20110013136
    Abstract: An electrically controllable optical component (10) comprises a transparent array of cells (3) and two transparent electrodes (5a, 5b) which are parallel and lying opposite each other on either side of the array of cells. Certain of the cells located between the two electrodes contain different electroactive materials, so that said cells exhibit different respective variations in at least one optical quantity in response to an electrical signal applied to the electrodes. An optical function is thus temporarily conferred on the component, resulting from gradients in the optical quantity that are formed parallel to the surface of the component.

  • Publication number: 20100283774
    Abstract: The invention relates to a transparent component (100) comprising active members (10) that are juxtaposed in parallel to a surface of the component, and that are each switchable between a transparent state and a reflecting state. Each active member establishes a light path between a light passage opening and a side of the component when said active member is reflecting. An addressing system (2) further controls the switching of the active members so that a reduced number of active members is simultaneously reflecting. Therefore, an image formed by transparency through the component thus appears permanently and continuously. Such a transparent component can be used for making an image superimposition device and an image display and storage device.

  • Patent number: 7828430
    Abstract: A transparent optical component comprises a set of cells (15) juxtaposed on a surface of the component. Each cell encloses a determined substance so as to endow the component with particular optical characteristics, and two neighbouring cells are separated by a wall (18). Some walls are not straight at the surface of the component, so that the light diffracted by the walls does not form any luminous glint or any flashing. In particular, the walls can be curved or made up of straight segments disposed end-to-end.

  • Patent number: 7808707
    Abstract: To produce a transparent optical element, the process starts with the production of an optical component having at least one transparent array of cells that are juxtaposed parallel to one surface of the component, each cell being hermetically sealed and containing a substance having an optical property. This optical component is then cut along a defined contour on its surface, corresponding to a predetermined shape of the optical element. Preferably, the array of cells constitutes a layer having a height of less than 100 ?m perpendicular to the surface of the component.

  • Publication number: 20100193112
    Abstract: A method sticks onto a curved surface of a substrate a functional film (4) that has a substantially planar initial shape. To this end, the film (4) is retained on a deformable membrane (1) by connecting means (2) that allow portions of said film to slip relative to the membrane when said membrane is deformed. This reduces stresses that are created in the film by the deformation. The method is adapted for applying a functional film to an ophthalmic lens.

  • Publication number: 20100039611
    Abstract: A transparent optical component having cells (1) filled with an optical material is proposed, which has a high transparency. The cells of the component are filled to levels (h1, . . . , h5) which vary randomly, and the variations of which are adapted so as not to cause a perceptible optical defect. To do this, the fill levels of the cells are adapted so that the phase shifts experienced by the light rays (R1, . . . , R5) which pass through the cells have a root mean square deviation of less than one quarter of the wavelength (1). Such a component may in particular be an ophthalmic lens.
