    Abstract: Fused silica glass having an internal transmittance of UV with 245 nm wavelength, being at least 95% at 10 mm thickness, a OH content of not larger than 5 ppm, and a content of Li, Na, K, Mg, Ca and Cu each being smaller than 0.1 ppm. Preferably the glass has a viscosity coefficient at 1215° C. of at least 1011.5 Pa·s; and a Cu ion diffusion coefficient of not larger than 1×10−10 cm2/sec in a depth range of greater than 20 μm up to 100 μm, from the surface, when leaving to stand at 1050° C. in air for 24 hours. The glass is made by cristobalitizing powdery silica raw material; then, fusing the cristobalitized silica material in a non-reducing atmosphere. The glass exhibits a high transmittance of ultraviolet, visible and infrared rays, has high purity and heat resistance, and exhibits a reduced diffusion rate of metal impurities, therefore, it is suitable for various optical goods, semiconductor-production apparatus members, and liquid crystal display production apparatus members.

    Abstract: The invention provides a process of obtaining a gradient index type of optical element with profiles of first and second metal component concentrations by the sol-gel method. The process of fabricating a gradient index type of optical element comprises steps of dipping a silicon component-containing wet gel prepared by the sol-gel method in a solution containing an alkoxide of at least one metal component selected from a first group consisting of Ti, Nb, Ta, and Zr or a derivative thereof to thereby impart to the wet gel a concentration gradient with a concentration of the first metal component decreasing from a periphery to a center of the wet gel, allowing at least one metal component selected from a second group consisting of Ba, La, Y, Gd, Sr, Ca, and Zn to be dissolved out of the wet gel to thereby impart to the wet gel a concentration gradient with a concentration of the second metal component increasing from the periphery to the center of the wet gel, and drying, and firing the wet gel.
