Abstract:
Disclosed is an ultraviolet and infrared absorptive glass characterized by that its coloring component contains, based on mass of the ultraviolet and infrared absorptive glass, 0.05-0.9 mass % of CeO2, 0.50-1.20 mass % of of total iron oxide in terms of Fe2O3, 0.08-0.30 mass % of FeO, 0.1-1.5 mass % of TiO2, 10-25 mass ppm of CoO, and 0.1-50 mass ppm of Cr2O3, that mass ratio (Fe2+/Fe3+) of divalent iron to trivalent iron is 0.20-0.45, and that dominant wavelength measured by using illuminant D65 of JIS Z 8701 is 510-560 nm. This glass has satisfactory optical characteristics, even though the content of CeO2 has been reduced.
