| titleOfInvention | Optical glass and optical product using the same |
| abstract | Provided is an optical glass having a high refractive index and high dispersion characteristics applicable to mass production of precision press molded products, mainly having optical constants of a refractive index nd in the range of 1.7 to 2.0 and an Abbe number nu d in the range of 20 to 32, and an optical part and a precision press molding material. An optical glass comprising as glass components, as molar percents, 12-34 percent of P2O5; 0.2-15 percent of B2O3 (where the total quantity of P2O5 and B2O3 is 15-35 percent); 0-45 percent of WO3; 0-25 percent of Nb2O5; 0 to 10 percent of TiO2 (where the total quantity of WO3, Nb2O5, and TiO2 is 20-45 percent); 0-25 percent of BaO; 0-20 percent of ZnO (where the total quantity of BaO and ZnO is less than 30 percent); 2-30 percent of Li2O; 2-30 percent of Na2O; 0-15 percent of K2O (where the total quantity of Li2O, Na2O, and K2O is 10-45 percent); 0-10 percent of CaO; 0-10 percent of SrO; 0-5 percent of Al2O3; 0-5 percent of Y2O3; 0-1 percent of Sb2O3; and 0-1 percent of As2O3; where the total quantity of all of the above-listed components is equal to or more than 94 percent. An optical part or precision press molding material comprised of this optical glass. <IMAGE> |
