Title (EN) COMPACT SPECTROFLUOROMETER
(FR) SPECTROFLUOROMETRE COMPACT
Abstract:
(EN) Spectrofluorometer (10) employing a pair of linear variable spectral filters (14, 18) to produce a three dimensional data output is disclosed. A collimated white light source (36) is used that first passes through a first linear variable spectral filter (14), then through a sample (16) where fluorescence occurs, then the resultant light passes through a second linear variable spectral light filter (18) that is oriented at ninety degrees from the first filter (14). The light is then detected by a CCD sensor (20) for conversion into data. This arrangement provides a very simple, rugged and compact instrument that can be used almost anywhere, such as at the scene of a contamination accident.
(FR) L'invention concerne un spectrofluoromètre (10) produisant une sortie de données tridimensionnelle au moyen de deux filtres (14, 18) spectraux variables linéaires. Une source (36) de lumière blanche collimatée passe d'abord à travers un premier filtre (14) spectral variable linéaire puis à travers un échantillon (16) où se produit la fluorescence, puis la lumière résultante passe à travers un second filtre (18) spectral variable linéaire orienté à quatre-vingt-dix degrés du premier filtre (14). La lumière est ensuite détectée par un détecteur (20) CCD qui la convertit en données. Ce arrangement permet d'obtenir un instrument robuste et compact, très simple, pouvant être utilisé quasiment partout, par exemple sur les lieux d'une contamination accidentelle.
