Abstract:
A method of producing an optical component for the transmission of UV light, said method comprising: preparing an optical fiber from synthetic quart glass or from doped synthetic quartz glass which is provided with a transmission region for the transmission of UV light, and charging the transmission region with hydrogen and/or with deuterium, said charging includinga) coating the fiber with a blocking layer inhibiting hydrogen diffusion, andb) charging the fiber in an atmosphere containing hydrogen and/or deuterium, said atmosphere being under a pressure in the range from 0.1 MPa to 200 MPa and at a temperature between 100.degree. C. and 800.degree. C. so as to produce a concentration of said hydrogen and/or deuterium of at least 5.times.10.sup.19 molecules/cm.sup.3 in the transmission region; andwherein the process steps a) and b) are performed repeatedly, said blocking layer being built up to comprise a plurality of thinner layers including a top layer, after application of which charging is discontinued.
