A liquid core waveguide (10) for fluorescence spectroscopy is provided. According to one version of the present invention, a substantially cylindrical support tube (30) is provided, having a substantially constant outer diameter, and a flexible tube (12) is wrapped in contiguous windings about the outer surface of the support tube (30) to form a tight coil about the support tube (30) which is configured of material that is transmissive of light in the relatively short wavelength range which is used to excite the molecular material in the flexible tube (12). This feature enables the flexible tube (12) to be wound tightly about the support tube (30) without crimping (thereby to form the liquid core waveguide into a compact package), and enables light in the relatively short excitation range to be effectively transmitted through the support tube (30) and into the flexible tube (12).
Cette invention se rapporte à un guide d'onde à noyau liquide (10) pour la spectroscopie par fluorescence. Dans l'une de ses variantes, cette invention utilise un tube de support essentiellement cylindrique (30), ayant un diamètre extérieur sensiblement constant et un tube flexible (12) est enroulé en enroulements contigus autour de la surface extérieure du tube de support (30), afin de former un enroulement serré autour du tube de support (30), lequel est conçu en un matériau qui est transparent à la lumière dans la gamme des longueurs d'onde relativement courtes utilisées pour exciter le matériau moléculaire dans le tube flexible (12). Cette caractéristique permet au tube flexible (12) d'être enroulé serré autour du tube de support (30), sans former de plis (constituant ainsi un guide d'onde à noyau liquide sous boîtier compact) et elle permet à la lumière comprise dans la gamme d'excitation relativement courte d'être transmise effectivement à travers le tube de support (30) jusque dans le tube flexible (12).
