Title (EN) IMPROVEMENTS IN AND RELATING TO SPECTROPHOTOMETERS
(FR) AMELIORATION CONCERNANT DES SPECTROMETRES
Abstract:
(EN) A beam of visible or UV light is directed by a sliding mirror (20) onto a diffraction grating (33) through each of a plurality of collimators (29 to 32) in turn. At each turn a photodiode array (35) measures the spectrum of a corresponding portion of the range of frequencies over which the instrument operates. A set of broad-band band-pass filters (16) may eliminate undesired frequencies at each turn.
(FR) Un miroir coulissant (20) oriente un faisceau de lumière visible ou ultraviolette sur un réseau de diffraction (33) à travers chacun d'une pluralité de collimateurs (29 à 32) tour à tour. A chaque changement d'orientation un réseau (35) de photodiodes mesure le spectre d'une partie correspondante de la plage de fréquences sur laquelle agit l'instrument. Un ensemble de filtres passe-bande (16) de large bande peut éliminer les fréquences non désirées à chaque changement d'orientation.
