Beschreibung
Zusammenfassung:	Glass compositions include one or more of tungsten oxide (W03), boron oxide (3203), lanthanum oxide (Lagoa), niobia (szOs), titania (TiOz) and zirconia (ZrOz) as essential components and may 5 optionally include yttria (Y203), barium oxide (BaO), calcium oxide (CaO), antimony oxide (szOa), P205 (phosphorus oxide), PbO (lead oxide), GeOz (germania) and other components. The glass compositions feature high refractive index and high transmittance in the blue portion of the electromagnetic spectrum.
