    Abstract: The space glasses have a composition, in wt. % based on oxide content, including SiO2, 12-45; B2O3, 0-4; Al2O3, 0-4; TiO2, 0-5; PbO, 50-82; Na2O, 0-4; K2O, 0-8; and at least 0.1 wt. % of a total amount of at least three doping agents selected from CeO2, MoO3, Bi2O3, WO3, Ag2O, SnO2, Sb2O3 and As2O3. Light-weight and space-saving optical systems for outer space applications can be made with these space glasses, which have high UV- and VIS-transmittance and high transmittance stability, because of their high radiation resistance based on their dopant content. A preferred process for making the space glass includes melting the above-stated oxide ingredients in a quartz crucible at 1050° C. to 1200° C. to form a melt and refining the melt at 1230° C. to 1350° C.

    Abstract: An optical glass for the manufacture of large transmission optics, such as lenses having a thickness of 100 millimeters or more, comprises 35 to 70 wt.-% SiO2, 17 to 35 wt.-% Al2O3, 3 to 17 wt.-% P2O5, 0 to 6 wt.-% Li2O, 0.5 to 4 wt.-% MgO, 0.5 to 3 wt.-% ZnO, a maximum of 1 wt.-% CaO, a maximum of 0.5 wt.-% BaO, 0.5 to 6 wt.-% TiO2, 0.5 to 3 wt.-% ZrO2, 0 to 1 wt.-% Na2O, 0 to 1 wt.-% K2O, a maximum of 1 wt.-% of refining agents (As2O3, SP2O3) and a maximum of 500 ppm of other contaminants. The glass composition may be equal to the composition of the glass ceramic Zerodur® and allows to manufacture large transmission optics in a cost-effective way, has a maximum of transmittance which is in the range of a He—Ne lasers and has a CTE of about 3·10−6/K.
