Abstract:
(EN) The purpose of the present invention is to provide an optical glass which has a unique combination of anomalous dispersion of a visible region and a near infrared region. The optical glass is characterized by: including, in mass%, 14 to 26% of SiO2, 9 to 16% of B2O3, and 10 to 42% of La2O3 as essential components; including ZnO, Y2O3, ZrO2, Ta2O5, Li2O, and Na2O, as optional components; and satisfying the relationships, 28 to 36% of SiO2+B2O3, 6 to 16% of ZrO2+Ta2O5, 43 to 59% of La2O3+Y2O3+ZnO, and 2 to 14% of Li2O+Na2O.
(FR) La présente invention vise à fournir un verre optique présentant une combinaison unique de dispersion anomale d'une région visible et d'une région de proche infrarouge.
