Abstract

L’invention concerne un spectromètre optique (10) comprenant : une ouverture (13) configurée pour recevoir un faisceau lumineux source, un premier système optique étant configuré pour recevoir le faisceau lumineux source et former un faisceau lumineux collimaté dirigé vers un réseau de diffraction, le réseau de diffraction étant configuré pour recevoir le faisceau lumineux collimaté et pour former un faisceau lumineux diffracté, un second système optique étant configuré pour former une image du faisceau lumineux diffracté sur un capteur d’image. Selon l’invention, le capteur d’image est un capteur CMOS comportant des pixels (34) agencés en N lignes orientées dans une direction inclinée à un angle alpha de la direction de diffraction spectrale de l’image du faisceau lumineux diffracté, où alpha est inférieur à 10 degrés, N est supérieur ou égal à 3, chaque pixel a une hauteur et une largeur définissant un rapport d’aspect du pixel supérieur à deux.
