APPARATUS FOR MAKING QUARTZ WORKPIECES OF FIBRE-OPTIC GUIDES Russian patent published in 2011 - IPC C03B37/14 C03B37/18 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of manufacturing tubular quartz workpieces of high-aperture, multimode fibre-optic guides. A core made from quartz glass doped with fluorine (n₁) is initially deposited, followed by a reflecting fluorosilicate classing with n₂<n₁. The apparatus - a microwave plasmatron for manufacturing quartz workpieces - is fitted with a sensor for monitoring microwave power reflected from the input of the plasmatron, a temperature sensor for the temperature of the rod, an electrically controlled attenulator connected between a master generator an amplifier, and a program for controlling the process of manufacturing workpieces of fibre-optic guides using a computer.

EFFECT: high efficiency of manufacturing quartz workpieces of light guides by widening the range of quartz workpieces, and low power consumption.
