Abstract

Die Erfindung bezieht sich auf eine Beleuchtungsanordnung für einen Filmabtaster mit einem Zeilensensor, einer Lichtquelle und einer optischen Einrichtung zur Erzeugen einer diffusen linienförmigen Beleuchtung auf dem Film. Die optische Einrichtung enthält einen Querschnittswandler (16) aus einem Bündel von Lichtleitern, der an einer Lichteintrittsfläche (15) einen flächigen Querschnitt und an einer Lichtaustrittsfläche (18) einen linienförmigen Querschnitt aufweist, und einen Integrationsstab (19), der das aus der Lichtaustrittsfläche des Querschnittswandlers (16) austretende Licht auf den Film leitet.
