摘要： A method of producing optical fiber preform includes: forming a deposited layer by depositing glass particles on a periphery of a target element in a deposition mode while burning a mixed gas containing a glass source material gas, a flaming gas, and a supporting gas by use of a flaming burner; maintaining a state where the supporting gas flows at a flow velocity greater than or equal to a flow velocity at which a nozzle end of the supporting gas discharge nozzles does not glow while maintaining a pilot burner by allowing the flaming gas to flow to the seal gas discharge nozzle after a seal gas is replaced with the flaming gas in a case where a mode is changed from the deposition mode to a non-deposition mode; and replacing the flaming gas flowing to the flaming gas port with a purge gas.

摘要： Fused silica injected or created by pyrolysis of SiCl4 are introduced in a powder state into a vacuum chamber. Pluralities of jet streams of fused silica are directed towards a plurality of heated substrates. The particles attach on the substrates and form shaped bodies of fused silica called preforms. For uniformity the substrates are rotated. Dopant is be added in order to alter the index of refraction of the fused silica. Prepared soot preforms are vitrified in situ. Particles are heated, surface softened and agglomerated in mass and are collected in a heated crucible and are softened and flowed through a heated lower throat. The material is processed into quartz plates and rods for wafer processing and optical windows.

摘要： A method of producing a glass-particle-deposited body that has a small diameter variation and the like resulting from alteration of the deposition condition is offered. When the glass-particle-deposited body is produced, a burner row constituted by placing a plurality of burners is moved relative to a starting member, and glass particles ejected from the burners are deposited on the starting member. In the method of producing a glass-particle-deposited body, alteration of the deposition condition is performed during the course of the deposition of the glass particles on the starting member. The method of producing a glass-particle-deposited body has a feature in that the alteration of the deposition condition is performed at least twice and that the burner positions along the length of the starting member at which the deposition condition is altered are placed at intervals shorter than the intervals between burners.

摘要： A known method for producing a cylindrical body uses a precipitation assembly (5) consisting of several precipitators (4), to which a parent substance is fed via medium supply lines (9), whereby the precipitation assembly (5) completes a closed trajectory (6) according to a predetermined displacement course, said trajectory comprising at least one precipitation path (8) that runs along the longitudinal axis (2) of the support. The aim of the invention is to provide an economical, reproducible, failsafe method based on said known procedure, which enables in particular the production of soot layers (3) on a support (1) at a high precipitation rate and nevertheless a high degree of uniformity. To achieve this, the displacement course (6) comprises a first loop (7a, 8) and a second loop (7b, 8), whereby the completion of the first loop (7a, 8) causes a right-hand torsion in the medium supply lines (9) and the completion of the second loop (7b, 8) causes a left-hand torsion in said lines (9).

摘要： A method for producing an optical fiber preform is provided in which the variation of the outer diameter in the longitudinal direction is minimized and a target quantity of glass is accumulated as a whole. Based on a predetermined relationship between three variables: the outer diameter of a starting rod being a first variable, the outer diameter of an optical fiber preform a second variable, and the timing for ending the glass particles depositing process a third variable, the starting rod and burners are subjected to relative reciprocating movement so as to deposit glass particles on the starting rod until the timing for ending the depositing process, and then the resulting deposit body is vitrified. The third variable may be the traverse velocity, the glass particles deposition time, or the weight of a soot glass deposit body.

摘要： The invention includes a method of incorporating fluorine into a preform that may be used to produce an optical article. A method that may be used to practice the invention includes a method of making an optical fiber preform. The method includes reacting a fluorine containing precursor in a flame of a combustion burner without forming a soot, thereby forming a fluorine doping atmosphere. A further method that may be practiced to practice the invention includes the step reacting at least a fluorine containing precursor in a flame of a combustion burner, wherein the precursors reacted in the flame are substantially devoid of the element of silicon, thereby forming a fluorine containing atmosphere for the doping of a soot preform. An additional method that may be used to practice the invention includes the step of reacting at least one precursor in the flame of a combustion burner, wherein said precursors comprise at least one fluorine containing compound and the precursors are substantially free of any silicon containing compound, and the additional step of directing a reaction product of said reacting step toward a soot preform.
