Abstract:
Glass compositions include phosphorus oxide (P2O5), niobia (Nb2O5), titania (TiO2), potassium oxide (K2O) and calcium oxide (CaO) as essential components and may optionally include barium oxide (BaO), sodium oxide (Na2O), lithium oxide (Li2O), tungsten oxide (WO3), bismuth oxide (Bi2O3), tantalum oxide (Ta2O5), silica (SiO2) and other components. The glasses may be characterized by high refractive index at 587.56 nm at comparably low density at room temperature.
