Title
(EN) ANTIMONY OXIDE GLASS WITH OPTICAL ACTIVITY
(FR) VERRE CONTENANT DE L'OXYDE D'ANTIMOINE ET OPTIQUEMENT ACTIF
Abstract
(EN) According to one aspect of the present invention an optically active glass contains Sb2O3, up to about 4 mole % of an oxide of a rare earth element, and 0-20 mole % of a metal halide selected from the group consisting of a metal fluoride, a metal bromide, a metal chloride, and mixtures thereof, wherein this metal is a trivalent metal, a divalent metal, a monovalent metal, and mixtures thereof. In addition, any of the glass compositions described herein may contain up to 15 mole % B2O3 substituted for an equivalent amount of Sb2O3.
(FR) Selon un mode de réalisation de la présente invention, un verre optiquement actif renferme du Sb2O3, jusqu'à environ 4 % en mole d'un oxyde d'élément de terre rare et de 0 à 20 % en mole d'un halogénure métallisé sélectionné à partir du groupe comprenant un fluorure de métal, un bromure de métal, un chlorure de métal et des mélanges de ceux-ci, ce métal étant un métal trivalent, un métal bivalent, un métal monovalent, et des mélanges de ceux-ci. En outre, selon la présente invention, toutes les compositions de verre décrites peuvent renfermer jusqu'à 15 % en mole de B2O3 substitué à une quantité équivalente de Sb2O3.
