Abstract

Die Erfindung bezieht sich auf eine Vorrichtung zum Erfassen von Eigenschaften einer bewegten Papierbahn (20), insbesondere zur Produktionskontrolle bei der Papierherstellung, mit einer IR-Beleuchtungseinrichtung (22), die geeignet ist, die Papierbahn (20) mit IR-Licht zu beleuchten und mit einer Nachweiseinrichtung (28) für von der Papierbahn (20) reflektiertes oder transmittiertes Licht, die einen Lichtaufnahmeteil aufweist. Die IR-Beleuchtungseinrichtung (22) weist einen langen, stabförmigen IR-Strahler (26) als Lichtquelle auf, dass diese Lichtquelle in einem Gehäuse (38) angeordnet ist, dass das Gehäuse (38) eine der Papierbahn (20) zugewandte Frontplatte (40) aufweist und dass in der Frontplatte (40) ein Austrittsfenster (48) abgedichtet angeordnet ist, durch das das Licht der Lichtquelle auf die Papierbahn (20) fällt.
