Abstract

Die Erfindung betrifft ein Spektrometer (1) zur Untersuchung der Inhaltsstoffe eines Fluids (2), mit einem Gehäuse (3) mit darin angeordneter Lichtquelle (4) und einem darin angeordneten Detektor (5), wobei das Licht der Lichtquelle (4) mit einem vorgegebenen Spektralbereich (Δλ) durch ein Sendefenster (7) durch das zu untersuchende Fluid (2) und durch ein Empfangsfenster (8) zu dem Detektor (5) geführt wird, wobei die Lichtquelle (4) durch mehrere mit einer Steuerelektronik (11) verbundene Leuchtdioden (10) gebildet ist, welche Leuchtdioden (10) zur Aussendung von Licht unterschiedlicher Wellenlängenbereiche (Δλi) innerhalb des vorgegebenen Spektralbereichs (Δλ) ausgebildet sind. Zur Schaffung eines möglichst kostengünstigen und mit geringer Baugröße aufgebauten Spektrometers (1) ist vorgesehen, dass der Detektor (5) zum Empfang des Lichts im gesamten vorgegebenen Spektralbereich (Δλ) und die Steuerelektronik (11) zur sequentiellen Ansteuerung der Leuchtdioden (10) ausgebildet ist, und gegenüber den Leuchtdioden (10) ein mit der Steuerelektronik (11) verbundener Kompensationsdetektor (12) angeordnet ist.
