    Abstract: The application of a mark on the surface of an ophthalmic glass of the type with an external hydrophobic and/or oleophobic coating with a low surface energy on a substrate or a coating with a high surface energy comprises: (a) positioning a mask, with a configuration complementary to the desired mark, between the surface to be marked and an energizing discharge source able to eliminate the external coating to reveal the underlying substrate or high energy coating; and (b) depositing on the outer coating, a temporary protective coating having a surface energy higher than that of the external coating and a thickness of less than 5 nm in order to allow the discharge to act on the external coating across the temporary protective coating.

    Abstract: A process for making a mould piece having a main curved surface bearing an utilitary microstructure which comprises transferring a utilitary microstructure from a master piece main surface to a main surface of a flat cured elastomeric film; pressing the cured elastomeric film and a master article against each other so as to conform the overall shape of said cured elastomeric film to the curved shape of the main surface of the master article and to spread over a curable coating composition between the curved main surface of the master article and the main surface bearing the replica of the said utilitary microstructure of the cured elastomeric film; curing the coating composition; removing the cured elastomeric film and depositing a layer of a metal or a metallic alloy on the exposed main surface of the hard coating of the master article; and recovering said metal or metallic alloy layer to obtain a mould piece having a curved main surface bearing a replica of said transferred utilitary microstructure.

    Abstract: The invention concerns a support of the type comprising at least a first base (13), and, borne by the latter, for maintaining such an optical lens (10) at its edge (11), at least three support pins (14A, 14B). The invention is characterized in that the base comprises, for its own support, a plane support surface (16) whereof the peripheral outline (P1) is globally circular, its radial dimension (D1) along a particular radius (R) of said support surface (16) is at least equal to its axial dimension (D2) perpendicularly to the plane thereof. The invention is particularly useful for maintaining an optical lens in a processing apparatus using spin coating technique.

    Abstract: Procédé de marquage d'un article optique (20) revêtu d'un revêtement interférentiel comprenant au moins deux couches intérieure (15) et extérieure (14) et de coefficient de réflexion Re ; par l'insolation de la couche intérieure (15) en un point de marquage (P), au moyen d'un faisceau laser à une longueur d'onde de marquage, de façon à ablater la couche intérieure et toute couche plus éloignée du substrat; la zone ablatée présentant un coefficient de réflexion Rm différent de Re d'au moins 1% ; La couche intérieure absorbant la longueur d'onde de marquage de manière plus importante que toute couche plus éloignée du substrat. L'invention concerne également un article optique revêtu d'un revêtement interférentiel à au moins deux couches intérieure et extérieure, ledit article comprenant un motif de marquage formé par absence localisée de couches.
