Abstract
Known methods for producing a semifinished product for an optical component of synthetic quartz glass of high homogeneity require a great number of forming or shaping steps for homogenization, which is troublesome in terms of energy and time and entails the risk that impurities might be introduced. To avoid these drawbacks, a method modification is suggested that comprises the following method steps: A blank suited for performing the method of the invention and shaped in the form of a substantially solid-cylinder SiOsoot body from successive SiOlayers is characterized in that most of the layers extend in parallel with the longitudinal axis of the soot body and in the direction of the outer surface of the soot body.
