(FR) VERRES SOLAIRES BRUNS ABSORBANT LES IR ET LES UV ET LENTILLES OPHTALMIQUES
Abstract:
(EN) The object of the present invention is brown solar glasses, absorbing UV or IR radiation, as well as solar ophthalmic lenses in said glasses. Said glasses have the following composition, expressed in percentages by weight: SiO2: 64 - 71; B2O3: 2 - 8; Al2O3: 0 - 4; ZrO2: 0 - 2; Li2O: 0 - 4; Na2O: 6 - 10; K2O: 7 - 16; CaO: 0 - 5.5; ZnO: 0 - 5.5; TiO2: 0 - 2; Fe2O3: 3 - 9; Co3O4: 0 - 0.030; NiO: 0 - 0.2; SeO2: 0.0030 - 0.1; As2O3: 0 - 0.1; Sb2O3: 0 - 0.1; SnO2: 0 - 0.1; C1: 0 - 2; Br: 0 - 2;F: 0 - 2.
(FR) La présente invention concerne des verres solaires bruns absorbant les rayonnements IR et UV, ainsi que des lentilles ophtalmiques solaires utilisées dans ces verres. Les verres de la présente invention présentent la composition suivante, exprimée en pourcentage en poids: SiO2: 64 - 71; B2O3: 2 - 8; Al2O3: 0 - 4; ZrO2: 0 - 2;Li2O: 0 - 4; Na2O: 6 - 10;K2O: 7 - 16; CaO: 0 - 5,5; ZnO: 0 - 5,5; TiO2: 0 - 2; Fe2O3: 3 - 9; CO3O4: 0 - 0,030; NiO: 0 - 0,2; SeO2: 0,0030 - 0,1; As2O3: - 0,1; Sb2O3: 0 - 0,1; SnO2: 0 - 0,1; Cl: 0 - 2; Br: 0 - 2; F: 0 - 2.
