    Abstract: The method involves obtaining a layer structure (4) comprising cells (1). An optical material e.g. powder, is introduced in each cell until average filling levels (h1-h5). Random or pseudo-random variations of the filling levels are introduced between the cells. The variations of the levels between the cells are determined such that phase differences of visible light rays (R1-R5), respectively crossing the cells along a direction (N) perpendicular to a convex surface (S1) of the structure, present root mean square that is fourteen times less than a wavelength of the light.

    Abstract: Un procédé permet de coller sur une surface courbe d'un substrat un film fonctionnel (4) qui possède une forme initiale sensiblement plane. Pour cela, le film (4) est retenu sur une membrane déformable (1) par des moyens de liaison (2) qui permettent à des parties dudit film de glisser par rapport à la membrane lorsque ladite membrane est déformée. De cette façon, des contraintes qui sont créées dans le film par la déformation sont réduites. Le procédé est adapté pour appliquer un film fonctionnel sur une lentille ophtalmique.

    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 method involves producing a transparent optical component comprising a set of juxtaposed cells parallel to a surface of the component, where each cell is hermetically sealed and contains a substance with optical property and the cells are separated by absorbing walls. The component is cut along a contour defined on the surface, corresponding to a shape determined for an optical element. Independent claims are also included for the following: (1) a transparent optical component (2) an ocular glass produced by cutting an optical component.

    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 optical blank (10) has a set of cells (15) juxtaposed in parallel to a blank surface, where each cell is hermetically sealed and contains a substance with an optical property. The set comprises cells of several sizes, where size of the cells is measured parallel to the surface and varied between different locations of the surface. The cells in a central zone of the surface have dimension greater than 0.5 millimeters and the cells in a peripheral zone of the surface have dimension lower than 100 micrometers. An independent claim is also included for an ocular glass.
