FIELD: manufacturing industry. SUBSTANCE: claimed method of manufacturing mobile light guide with smooth circular refraction coefficient profile comprises heating quartz tube by outside oxygen or hydrogen burner at temperatures from 1875 to 1903 C and feeding mixture including 5200 mg/m $$$, 430 mg/m $$$, 30 mg/m $$$ and 9 sq.cm/m $$$ for spraying first coating onto quartz tube. Raw material including 3300 mg/m $$$, 1150 mg/m $$$, 20 mg/m $$$ and 1500 cubic cm/m $$$ is then added into quartz tube at constant temperature of 190 C for spraying circular zone. Mixture including 3800 mg/m $$$, 430 mg/m $$$, 10 mg/m $$$ and 7 cubic cm/m $$$ is then added into quartz tube at constant temperature from 1890 to 1897 C for spraying second coating. This done, core is sprayed, light guide is condensed, etched, sealed and closed. EFFECT: creation of uncurving refraction coefficient of light guide. 7 cl, 5 dwg, 3 tbl øøø1 |
