摘要： In a known method for the production of a blank mold for optical fibers, a fluorine-doped SiO2 enveloping glass is produced on a core glass cylinder that rotates about its longitudinal axis, wherein a silicon-containing starting substance is fed to a plasma burner, said substance is then oxidized in a plasma flame assigned to the plasma burner to obtain SiO2 particles, the SiO2 particles are deposited by layers on the enveloping surface of the cylinder of the core glass cylinder in the presence of fluorine and sintered into the enveloping glass. The invention aims at providing an economical method, which builds upon the above-mentioned method, in order to produce a blank mold from which optical multi-mode fibers (52) can be obtained. In comparison with fibers (51) produced according to standard methods, said optical multi-mode fibers are characterized by high initial transmission in the UV wavelength range and good resistance with respect to brief UV radiation, more particularly in the 210-300 nm wavelength range. According to the invention, a plasma flame that irradiates an ultraviolet light having a wavelength of 214 nm with an intensity of at least 0.9 μW—determined on the basis of plasma flame intensity measurement—is used for the formation and deposition of the SiO2 particles on the core glass.

摘要： A core glass for making a preform for an optical fiber particularly useful for the transmission of ultraviolet radiation and methods for making the core glass are disclosed. The core glass is obtained by the flame hydrolysis of a silicon compound, deposition of finely granular SiO2 on a substrate with direct vitrification and formation of a synthetic quartz glass. The quartz glass has a hydrogen content of less than 1×1018 molecules/cm3.

摘要： In a known optical component a cylindrical glass core of synthetic quartz glass contains hydroxyl groups, a maximum 200 wt.-ppm of chlorine, and no dopant in the form of a metal oxide. The glass core is axially enveloped by a glass mantle of doped quartz glass which has a lower refractive index than the glass core. Setting out from this, in order to offer an optical component of quartz glass for broad-band transmission, especially for broad-band spectroscopy, which is characterized by low attenuation over a broad range of wavelengths, it is proposed by the invention that the core glass contain less than 5 wt.-ppm of hydroxyl groups.
