Abstract
This method for drawing a quartz glass optical component shortens the pulling process and minimizes loss of material. An end face of a quartz glass hollow cylinder forms a tapered end portion to an attachment piece of quartz glass having a bore. The inner bore of the hollow cylinder and the bore of the attachment piece are at least temporarily interconnected fluidically as a passage bore. A cleaning fluid is passed through the inner bore of the hollow cylinder and the passage bore. A core rod of quartz glass, which rests on a contact surface of the attachment piece, is inserted into the inner bore of the hollow cylinder, and the hollow cylinder is continuously supplied to a heating zone, heated therein so as to form a drawing bulb, and the component is continuously drawn therefrom.
