Abstract:
(EN) Provided are: an optical glass that has good chemical durability, a small specific gravity, and optical characteristics including a medium refractive index and low dispersion; and a preform material and an optical element using the optical glass. The optical glass contains: 0% or more but less than 30.0% of a SiO2 component; 8.0-30.0% of an Al2O3 component; a total mass of less than 20.0% of an RO component (in the formula, R is one or more substances selected from the group consisting of Zn, Mg, Ca, Sr, and Ba); and a total mass of 10.0-55.0% of a Ln2O3 component (in the formula, Ln is one or more substances selected from the group consisting of La, Gd, Y, and Lu). The mass ratio of (SiO2+Al2O3)/B2O3 is 0.3-10.0. The optical glass has a refractive index (nd) of 1.58-1.80 and an Abbe number (νd) of 35-65.
(FR) L’invention fournit un verre optique qui possède des caractéristiques optiques d’indice de réfraction moyen / faible dispersibilité, et qui présente une durabilité chimique satisfaisante et un petit poids spécifique, et fournit également un matériau de préforme et un élément optique mettant en œuvre ce verre optique. Le verre optique de l’invention comprend 0 à moins de 30,0% d’un composant SiO, 8,0 à 30,0% d’un composant Al, un composant RO de somme en masse inférieure à 20,0% (dans la formule, R consiste en au moins un élément choisi dans un groupe constitué de Zn, Mg, Ca, Sr et Ba), et un composant Ln de somme en masse comprise entre 10,0 et 55,0% (dans la formule, Ln consiste en au moins un élément choisi dans un groupe constitué de La, Gd, Y et Lu). Ce verre optique présente un rapport massique (SiO+Al)/B compris entre 0,3 et 10,0, un indice de réfraction (n) supérieur ou égal à 1,58 et inférieur ou égal à 1,80, et un nombre d’Abbe (ν) supérieur ou égal à 35 et inférieur ou égal à 65.
(JA) 中屈折率低分散の光学特性を有し、良好な化学的耐久性及び比重の小さい光学ガラスをと、これを用いたプリフォーム及び光学素子を提供する。 光学ガラスは、SiO成分 0~30.0%未満、Al成分を8.0%~30.0%、RO成分(式中、RはZn、Mg、Ca、Sr、Baからなる群より選択される1種以上)の質量和が20.0%未満、Ln成分(式中、LnはLa、Gd、Y、Luからなる群より選択される1種以上)の質量和が10.0%~55.0%含有し、 質量比(SiO+Al)/Bが0.3~10.0であって、1.58以上1.80以下の屈折率(n)を有し、35以上65以下のアッベ数(ν)を有する。
