Abstract: Methods, apparatus and precursors for producing substantially water-free silica soot, preforms and glass. The methods and apparatus make substantially water-free fused silica preforms or glass by removing water as a reaction product, removing water from the atmosphere, removing water from the transport process, or combinations thereof. In a first embodiment, substantially water-free soot, preforms or glass are achieved by using a hydrogen-free fuel, such as carbon monoxide, in the deposition process. In another embodiment, a soot producing burner has parameters that enable operation on a substantially hydrogen-free fuel. End burners, which minimize water production, are also described. Such water-free methods are useful in depositing fluorine-doped soot because of the low water present and the efficiency in which fluorine is incorporated. In another embodiment, glassy barrier layer methods and apparatus are described for minimizing dopant migration, especially fluorine. Laser and induction methods and apparatus for forming the barrier layer are depicted. A chlorine, fluorine and silica precursor, such as chlorofluorosilane, may be utilized to form fluorinated soot. Other methods and apparatus are directed to combinations of conventional and substantially water-free processes. One embodiment is directed to combustion enhancing additives for addition to the substantially hydrogen-free fuels. The methods and apparatus in accordance with the invention are particularly useful for producing photomask substrates and optical fiber preforms.

Abstract: An on-line thickness gauge (OLTG) and method are described herein that are capable of measuring a thickness of a moving glass substrate. In the preferred embodiment, the OLTG includes a Y-guide and a stabilizing unit that respectively captures and stabilizes the moving glass substrate. The OLTG also includes a laser instrument which contains a laser source and a detector. The laser source emits a beam at the front surface of the moving glass substrate. And, the detector receives two beams one of which was reflected by the front surface of the moving glass substrate and the other beam which was reflected by the back surface of the moving glass substrate. The OLTG further includes a processor that analyzes the two beams received by the detector to determine a distance between the two beams which is then used to determine the thickness of the moving glass substrate.
