Abstract:
An optical component (10) comprises a transparent set of cells (15 ; 25) juxtaposed in parallel to a surface of the component. Each cell is hermetically sealed and contains a substance with an optical property. The set of cells comprises cells of several sizes. The size of the cells can be varied between various locations of the surface of the component (10), for making it possible to cut out the component without altering its optical properties . Furthermore, the variation in size of the cells serves to prevent diffraction or scattering from being visible in certain zones of the component.
Abstract:
The invention concerns a transparent optical component (10) comprising at least one transparent set of cells (15) juxtaposed parallel to a surface of the component, each cell being separated by walls (18) with apodized profile parallel to the surface of the component, and each cell being hermetically sealed and containing at least one substance with optical property. The cells (15) can in particular have a Gaussian profile of walls. The invention also concerns a method for making such an optical component as well as its use for making an optical element. The optical element can in particular be a spectacle lens.
Abstract:
The invention relates to the sealing of a cellular structure (10) along a periphery that includes forming a furrow (S) in said structure, and depositing a portion (11) of a binding material in contact with the respective edges (B1, B3) of a bearing film (1) and of a sealing film (3) of the structure. The binding material may consist of a glue or a welding material. The binding material is cured for definitively connecting the bearing film and the sealing film along the periphery. Such a method is adapted for tightly closing a flexible cellular structure for the optical functionalisation of an ophthalmic lens, in particular when said structure is cut in a sheet.
Abstract:
The invention relates to a transparent film comprising a base film (1) and a coating arranged in separate portions (2a) on a face of the base film (S1). The coating comprises an inorganic/organic hybrid or inorganic material. Separation lines (3) between the portions of the coating enable the film to be deformed without visible defects appearing in the coating. The film can then be applied to a curved surface (SO) of an optical element, such as an ophthalmic lens (10).
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.
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 neighbours 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.
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.

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.
Abstract:
The invention relates to transparent electrochromic systems (100) which each include one pair of supply electrodes (1, 2) and at least one pair of polarisation electrodes (3, 4). The polarisation electrodes prevent a reaction of mutual neutralisation of the electroactive substances of the systems from causing unnecessary consumption of electric current. Said electrodes also prevent a neutralisation reaction from limiting a lower value of light transmission of the systems. For this purpose, the polarisation electrodes produce an electric field (E) inside the systems, which attracts the electroactive substances that have already reacted with the supply electrodes to different areas.
