Process for improving the geometry of a glass tube used for making fibre optic preforms |
摘要 |
<p>A silica glass tube with a non geometrically uniform cross-section is treated by determn. the point (G) on the tube surface where the thickness difference is greatest. A heating device is then passed along the tube surface at this point while a reactive gas is flowed through the inside of the tube.</p> |
