Title (EN) THERMALLY STRENGTHENED GLASS SHEETS HAVING SMALL-SCALE INDEX OR BIREFRINGENCE PATTERNS
(FR) FEUILLES DE VERRE RENFORCÉES THERMIQUEMENT PRÉSENTANT DES MOTIFS D'INDICE DE RÉFRACTION OU DE BIRÉFRINGENCE RÉDUITS
Abstract:
(EN) A strengthened glass or glass ceramic sheet has a roughness of greater than 0.05 nm Ra and less than 0.08 nm Ra over an area of 10 µm x 10 µm and has the property that, excluding areas within three sheet thicknesses of the outer edge surface of the sheet, the slope of a measured value of a thermally affected property of glass over distance along the first major surface of the sheet is higher bordering one or more lower-cooling-rate-effect-exhibiting areas on the first surface of the sheet than elsewhere on the first surface of the sheet, and at least one of said one or more areas has a shortest linear dimension, in a direction parallel to the first major surface, of less than 100000 µm.
(FR) Une feuille de verre ou de vitrocéramique renforcée présente une rugosité supérieure à 0,05 nm Ra et inférieure à 0,08 nm Ra sur une surface de 10 µm × 10 µm et a la propriété que, à l'exception de zones dans trois épaisseurs de la surface du bord extérieur de la feuille, la pente d'une valeur mesurée d'une propriété de verre thermiquement affectée sur une distance le long de la première surface principale de la feuille, délimitant une ou plusieurs zones présentant un effet de vitesse de refroidissement inférieure sur la première surface de la feuille, est plus importante qu'à un quelconque endroit sur la première surface de la feuille, et au moins l'une desdites une ou plusieurs zones a une dimension linéaire raccourcie, dans une direction parallèle à la première surface principale, inférieure à 100 000 µm.
