OPTICAL HOLLOW WAVEGUIDE ASSEMBLY

摘要

The invention concerns an optical hollow waveguide assembly (1) comprising an optical hollow waveguide (2) for guiding illuminating light (3). The hollow waveguide (2) has a tubular base member (6) with a continuous waveguide cavity (7). The cavity has an illuminating light inlet (8) and an illuminating light outlet (9). A cavity inner wall (10) of the waveguide cavity (7) is designed to be highly reflective for the illuminating light (3) under grazing incidence. A gas source (12) is fluidically connected (13) to the waveguide cavity (7). As a result, a hollow waveguide assembly is produced in which the risk of contamination of the hollow waveguide is low..
