Abstract
The present invention relates to a quartz glass blank for an optical component for transmitting radiation of a wavelength of 15 nm and shorter, the blank consisting of highly pure quartz glass, doped with titanium and/or fluorine, which is distinguished by an extremely high homogeneity. The homogeneity relates to the following features: Said quartz glass blank can only be obtained in that a doped quartz glass obtained by flame hydrolysis of a compound containing silicon, titanium and/or fluorine is formed as a large volume rod-shaped starting body into a homogeneous quartz glass blank using several forming steps and is homogenized.
