Publication number: 20150176202Abstract: A selective dyeing method is used for dyeing a substrate, selectively within a first exposed surface portion of said substrate. For this purpose, the substrate consists of a material that is impervious to a dye with the exception of the first portion of the exposed surface. In particular, the impervious material can form a layer which covers a base portion of the substrate in a second portion of the exposed surface. The substrate is heated such that the dye penetrates a pervious material which constitutes the first portion of the exposed surface. The method is particularly useful for eliminating light diffused by the walls of a multilayer structure which is supported by means of ocular glass.Type: ApplicationFiled: March 4, 2015Publication date: June 25, 2015Inventors: Samuel Archambeau, Jérôme Ballet, Jean-Paul Cano, Stéphane Perrot

Patent number: 9001282Abstract: A variable power optical element is divided into cells which contain two liquid crystals mixed according to different proportions. The proportion of one of the liquid crystals in each cell increases on the basis of the radial distance between a central point of the optical element and said cell. An appropriate selection of the two liquid crystals results in a higher variation of the optical power between two control states of said optical element. More particularly, the optical element may consist of an ophthalmic lens which changes between a convergent lens state and a divergent lens state.Type: GrantFiled: December 14, 2009Date of Patent: April 7, 2015Assignees: Essilor International (Compagnie Generale d'Optique), Centre National de la Recherche Scientifique—CNRSInventors: Samuel Archambeau, Henri Camon, Solon Mias

Patent number: 8999006Abstract: The invention relates to a selective dyeing method used for dyeing a substrate (10), selectively within a first exposed surface portion (S1) of said substrate. For this purpose, the substrate consists of a material (2) that is impervious to a dye with the exception of the first portion of the exposed surface. In particular, the impervious material can form a layer which covers a base portion (3) of the substrate in a second portion (S2) of the exposed surface. The substrate is heated such that the dye (C) penetrates a pervious material (1) which constitutes the first portion of the exposed surface. The method is particularly useful for eliminating light diffused by the walls of a multilayer structure which is supported by means of ocular glass.Type: GrantFiled: October 15, 2010Date of Patent: April 7, 2015Assignee: Essilor International (Compagnie Generale d'Optique)Inventors: Samuel Archambeau, Jérôme Ballet, Jean-Paul Cano, Stéphane Perrot

Patent number: 8814352Abstract: Method for producing a plastic film containing a compound absorbing ultraviolet radiation comprising (a) depositing an alcoholic solution of polyvinyl butyral on a transparent plastic support film, (b) evaporating the solvent from the alcoholic solution of polyvinyl butyral so as to form a polyvinyl butyral layer on the transparent support film, (c) printing the polyvinyl butyral layer with an ink absorbing ultraviolet radiation (UV absorber) in a pattern, (d) heating the transparent plastic support film, coated with the printed polyvinyl butyral layer so as to enable at least part of the UV absorber to pass from the polyvinyl butyral layer to the plastic support film, (e) removing the polyvinyl butyral layer, preferably by washing with a suitable solvent. The application also relates to the film obtained by this method and the use of this film for producing a photochromic element with a spatially non-uniform behavior.Type: GrantFiled: November 9, 2010Date of Patent: August 26, 2014Assignee: Essilor International (Compagnie Generale d'Optique)Inventors: Samuel Archambeau, Christian Bovet, Stephane Perrot

Patent number: 8801177Abstract: 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.Type: GrantFiled: October 17, 2007Date of Patent: August 12, 2014Assignee: Essilor International (Compagnie Generale d'Optique)Inventors: Samuel Archambeau, Jean-Paul Cano, Christian Bovet

Patent number: 8736946Abstract: The invention relates to transparent electrochromic systems which each include one pair of supply electrodes and at least one pair of polarization electrodes. The polarization electrodes prevent a reaction of mutual neutralization of the electroactive substances of the systems from causing unnecessary consumption of electric current. Said electrodes also prevent a neutralization reaction from limiting a lower value of light transmission of the systems. For this purpose, the polarization electrodes produce an electric field inside the systems, which attracts the electroactive substances that have already reacted with the supply electrodes to different areas.Type: GrantFiled: September 24, 2010Date of Patent: May 27, 2014Assignee: Essilor International (Compagnie Generale d'Optique)Inventors: Samuel Archambeau, Claudine Biver, Christian Bovet, Jean-Paul Cano, Sandrine Duluard, Anthony Saugey

Patent number: 8134782Abstract: 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.Type: GrantFiled: January 15, 2008Date of Patent: March 13, 2012Assignee: Essilor International (compagnie Generale d'optique)Inventors: Samuel Archambeau, Christian Bovet, Jean-Paul Cano, Sylvie Vinsonneau

Patent number: 7878649Abstract: An optical element comprises a base component (1) provided with a set of cells (10) open on a face of the component and a film (2) for sealing the cells. The film is adhesively bonded to ends (12) of separation walls (11) present between the cells. The adhesive bonding is carried out by applying a pressure adjusted so that the ends of the walls penetrate into a layer of adhesive material (3) positioned between the film and the set of cells. A refractive index value of the adhesive material is adjusted with respect to a value of the same index for the material of the ends of the walls m order to obtain an optical element which exhibits a high transparency.Type: GrantFiled: June 8, 2007Date of Patent: February 1, 2011Assignee: Essilor International (Compagnie General d'Optique)Inventors: Samuel Archambeau, Jerome Ballet, Jean-Paul Cano, Anthony Saugey
