20100118260 | PIXELIZED OPTICAL COMPONENT WITH NANOWALLS - 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. | 05-13-2010 |
20110033802 | METHOD FOR PREPARING A PHOTO-CROSSLINKABLE COMPOSITION - The invention relates to a photo-crosslinkable composition that can be obtained by a method including the following steps: (a) the hydrolysis and condensation reaction of a [(epoxycycloalkyl)alkyl]thalkoxysilane in solution in an organo-aqueous medium containing water in an initial water/monomer molar ratio of between 3 and 15, with at least one water-soluble solvent, at a pH of between 1.6 and 4.0, by heating the solution to a temperature of between 50 and 70° C. for a duration of between 180 and 350 minutes in order to obtain a solution of an organo-mineral hybrid prepolymer, in which the totality or quasi-totality of the alkoxysilane groups has been hydrolysed, and which comprises in average at least 4 (epoxycycloalkyl)alkyl groups; (b) cooling the polyepoxide prepolymer composition thus obtained down to a temperature of between 15 and 25° C.; (c) adding to said composition at least one cationic-polymerisation photo-primer and at least one photosensitiser having a maximum absorption at a wavelength of between 300 and 420 nm, and optionally adding a surfactant; (d) agitating the composition thus obtained for a duration of between 10 and 120 minutes at a temperature of between 15 and 25° C.; (e) filtering the composition thus obtained with a filter comprising pores with an average size of between 1 and 5 μm; and (f) storing the liquid filtrate thus obtained at a temperature lower than 0° C., preferably between −20 and −10° C. The invention also relates to the use of such a photocrosslinkable composition as a negative photosensitive resin in a photolithography process. | 02-10-2011 |
20110043925 | OPTICALLY TRANSPARENT COMPONENT WITH TWO SETS OF CELLS - A transparent optical component comprises two sets of cells (1) disposed in respective superposed layers (10, 20). Each cell (1) contains an optically active material, and the cells in each set are isolated from one another by separating portions (2) within the corresponding layer. The cells (1) of one layer are offset relative to the cells of the other layer so as to be located in line with the separating portions (2) pertaining to the other layer. Such optical component exhibits transparency that is improved compared with components having a single layer of cells or cells that are superposed. | 02-24-2011 |
