Abstract
Spectromètre destiné à mesurer les intensités d'énergie d'un faisceau lumineux pour différentes longueurs d'ondes. Le faisceau de lumière issu de la fente 30, passant par l'échantillon 11, vient frapper deux réseaux 32 et 34 comportant des traits parallèles à la fente 30 et ayant pour fonction de répartir la lumière en deux faisceaux séparés qui sont ensuite focalisés par les dispositifs optiques 40 et 42 sur les assemblages de photodiodes 44 et 46, ceux-ci fournissant des signaux de sortie proportionnels à l'intensité des raies des spectres d'énergie des faisceaux. Un tel spectromètre présente l'avantage de fonctionner sur une large bande de longueurs d'onde sans utiliser de parties mobiles.
