Optical toughened glass
The invention provides an optical toughened glass. The glass comprises SiO2, CaO, MgO, Al2O3, Na2O, B2O3, K2O, BaO, MoO3, CdO, La2O3, Gd2O3, Y2O3 and Yb2O3. After expensive Ta2O5 is discarded, the glass having excellent glass stability, high refractive index and low chromatic dispersion is obtained through adopting the co-existence form of the La2O3, Gd2O3, Y2O3 and Yb2O3, MoO3 can reduce the generation amount of nickel sulfide stones, and MoO3 and CdO are mixed to inhibit smoke generated in the glass production process, so the safety in the glass production process is ensured, and the self-explosion possibility of the glass is reduced.
