UV-STABILIZED SILICA-BASED FIBER FOR APPLICATIONS AROUND 200 NM WAVELENGTH

New optical fibres having a nearly constant UV transmission at around a wavelength of 200 nm have been fabricated for the first time. Due to their improved UV properties when compared to those commercially avai lable, these new fibres are tested as a potential transmission medium for the broadband spectrum of a deuterium lamp. In addition, a complet e sensor system, including the lamp itself and the associated optical system, will be described in light of its intended application to spec troscopic chemical measurements. Details of the spectral intensities a t the output of such a fibre, of 1 m length appropriate for such syste ms, are given in this work.
