  • Device for generating an optically homogeneous, streak-free quartz glass body having a large diameter
    Patent number: 6595030
    Abstract: A device for producing optically homogeneous, streak-free quartz glass bodies having a large diameter including a furnace or melting device having an inner chamber with a pair of openings opposite one another. One or more movable burners are displaceable into one of the openings and the respective glass body to be produced is located in the other opening. Both the burner and glass body are movably positioned. In the course of the production of the quartz glass body, a relative movement is effected in the axial and radial directions between the burner and the quartz glass body such that the distance from the burner outlet opening pertaining to the quartz glass body decreases as the distance from the burner to the X-X axis of the quartz glass body increases.
