PRECISION PRESSED OPTICAL COMPONENTS MADE OF GLASS AND GLASS SUITABLE THEREFOR

摘要

Optical components can be pressed with such a precision that grinding and polishing of the formed components is not necessary, from glasses containing 45-55 wt. % P2O5, 3.5-9 wt. % Al2O3, 5-20 wt. % K2O, 0-3 wt. % Li2O, 8-15% BaO, 4.5-9 wt. % ZnO, 0-6 wt. % MgO, 0-18 wt. % PbO, 0-1 wt. % SiO2, 0-3 wt. % B2O3, 0-2 wt. % TiO2.
