    Abstract: The component has a set of cells (15) juxtaposed along a meshing of a surface of the component. Each cell contains a substance providing particular optical property to the component. Two neighboring cells are separated by a wall (18) extending perpendicular to the surface. Each wall extends between two ends of the wall that corresponds to nodes (N) of the meshing. Some of the walls are not rectilinear to the surface. An independent claim is also included for an optical element obtained by cutting of a transparent optical component.

    Abstract: The method involves producing an optical component (10) having a transparent assembly of cells (15) juxtaposed in parallel at a surface of the component. Each cell is hermetically closed. The component is cut along a defined contour on its surface related to a determined shape for a transparent optical unit. The component is drilled for fixing the optical unit on a maintenance support such as a frame. Independent claims are also included for the following: (A) an optical component (B) an ocular glass produced by cutting an optical component.

    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: Un système électrochrome transparent (100) comprend une structure cellulaire (13), deux électrodes d'alimentation (1, 2) qui sont portées ensemble par une même paroi (10), et au moins une électrode supplémentaire (3). Ladite électrode supplémentaire peut être utilisée comme électrode de référence ou électrode de polarisation. Elle peut aussi former un condensateur avec une quatrième électrode qui est ajoutée au système, pour contrôler une migration de certaines substances électroactives responsables de la coloration et de la décoloration du système. Le fonctionnement du système peut ainsi être amélioré.

    Abstract: The invention relates to a method for producing an ophthalmic lens exhibiting optical function coexisting in producing an optical component (10) incorporating at least one type of active material (2) which is distributed in a parallel direction to the surface thereof. Said active material exhibits a radiation-modifiable optical property. The active material (5) portions disposed through the component (10) surface are, afterwards, selectively irradiated in such a way that the optical function is obtainable by modulating said property from one portion to another one, wherein the sizes of said portions are less than 1 mm.

    Abstract: The invention relates to a method of producing a substrate which is coated with a mesoporous layer and to the use thereof in ophthalmic optics. The inventive method comprises the following steps comprising: preparing a precursor sol containing (i) a precursor agent that is selected from compounds having formula M(X)4 (I), in which X is a hydrolysable group and M represents silicon or a tetravalent metal and mixtures thereof, (ii) at least one organic solvent, (iii) at least one pore-forming agent and (iv) water; depositing a film of the precursor sol on a main surface of the substrate; optionally consolidating the mesoporous structure of the deposited film; eliminating the pore-forming agent; and recovering the substrate coated with the mesoporous layer. The method is characterized in that: (i) the pore-forming agent is eliminated at a temperature of less than or equal to 150° C.; and (ii) the method comprises a step involving the introduction of at least one reactive agent bearing at least one hydrophobic group, before the deposition step and/or after said step.

    Abstract: The present invention relates to methods of incorporating additives into a thin film formed on a substrate comprising: forming an impregnatable thin film on at least one face of a substrate; depositing an impregnation composition comprising at least one additive incorporated in an appropriate diluent medium on said impregnatable thin film by spin coating; diffusing the impregnation composition within said impregnatable thin film and; treating the substrate coated with the impregnated thin film to at least partially remove the diluent medium from the impregnated thin film. The invention also relates to the application of such methods to the production of optical lenses, including in the colouring of such lenses.
