    Abstract: In a known method, a quartz glass component is produced for a UV radiation source by melting SiO2-containing grain. Starting therefrom, to indicate an inexpensive method by means of which a quartz glass component is obtained that is characterized by high radiation resistance, it is suggested according to the invention that synthetically produced quartz crystals are molten to obtain a pre-product which consists of quartz glass containing hydroxyl groups in a number greater than the number of SiH groups, and that for the elimination of SiH groups the pre-product is subjected to an annealing treatment at a temperature of at least 850° C., whereby the quartz glass component is obtained. In the quartz glass component of the invention, the quartz glass is molten from synthetically produced quartz crystals, and it has a content of SiH groups of less than 5×1017 molecules/cm3.

    Abstract: What is disclosed includes OD-doped synthetic silica glass capable of being used in optical elements for use in lithography below about 300 nm. OD-doped synthetic silica glass was found to have significantly lower polarization-induced birefringence value than non-OD-doped silica glass with comparable concentration of OH. Also disclosed are processes for making OD-dopes synthetic silica glasses, optical member comprising such glasses, and lithographic systems comprising such optical member. The glass is particularly suitable for immersion lithographic systems due to the exceptionally low polarization-induced birefringence values at about 193 nm.
