Abstract:
Glass compositions include niobia (Nb2O5), phosphorus oxide (P2O5) and titania (TiO2) as essential components and may optionally include calcium oxide (CaO), potassium oxide (K2O), barium oxide (BaO), sodium oxide (Na2O), lithium oxide (Li2O), magnesia (MgO), zinc oxide (ZnO) and other components. The glasses may be characterized by high refractive index at 587.56 nm at comparably low density at room temperature.
