Method of producing internally coated glass tubes for the drawing of fiber-optic light conductors |
摘要 |
The change in the refractive index across the radius which is important for self-focussing fibre optic light conductors is obtained because in the plasma-activated CVD-method the oxygen content of the gas mixture and/or the temperature of the tube wall is continuously reduced during the coating procedure.
