Claims (7)

1. Beleuchtungsanordnung für einen Filmabtaster mit einem Zeilensensor, einer Lichtquelle und einer optischen Einrichtung zum Erzeugen einer diffusen linienförmigen Beleuchtung auf dem Film, dadurch gekennzeichnet, dass die optische Einrichtung
  • - 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) umfasst, der das aus der Lichtaustrittsfläche des Querschnittswandlers (16) austretende Licht auf den Film leitet.
1. Illumination arrangement for a film scanner with a line sensor, a light source and an optical device for generating a diffuse linear illumination on the film, characterized in that the optical device
  • - A cross-sectional converter ( 16 ) from a bundle of light guides, which has a flat cross-section on a light entry surface ( 15 ) and a linear cross-section on a light exit surface ( 18 ), and
  • - Includes an integration rod ( 19 ) which directs the light emerging from the light exit surface of the cross-sectional converter ( 16 ) onto the film.
2. Beleuchtungsanordnung nach Anspruch 1, dadurch gekennzeichnet, dass der Integrationsstab (19) ein Kaleidoskopstab ist und im wesentlichen einen Querschnitt in Form eines langgestreckten Rechtecks aufweist.2. Lighting arrangement according to claim 1, characterized in that the integration rod ( 19 ) is a kaleidoscope rod and essentially has a cross section in the form of an elongated rectangle. 3.

Lighting arrangement according to one of the preceding claims, characterized in that the light exit surface ( 18 ) of the cross-sectional converter ( 16 ) is almost linear. 4. Beleuchtungsanordnung nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass die Lichteintrittsfläche (15) des Querschnittswandlers (16) rechteckförmig ist. 4. Lighting arrangement according to one of the preceding claims, characterized in that the light entry surface ( 15 ) of the cross-sectional converter ( 16 ) is rectangular. 5. Beleuchtungsanordnung nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass zwischen der Lichtquelle (1) und der Lichteintrittsfläche (15) des Querschnittswandlers (16) mindestens eine Kondensorlinse (4, 5), Filter (11, 12) und ein weiterer Integrationsstab (7) angeordnet sind.5. Lighting arrangement according to one of the preceding claims, characterized in that between the light source ( 1 ) and the light entry surface ( 15 ) of the cross-sectional converter ( 16 ) at least one condenser lens ( 4 , 5 ), filter ( 11 , 12 ) and a further integration rod ( 7 ) are arranged. 6. Beleuchtungsanordnung nach Anspruch 5, dadurch gekennzeichnet, dass die Länge des weiteren Integrationsstabes (7) derart bemessen ist, dass die Struktur des Wendelbildes durch mehrmalige Spiegelung an den Außenflächen unterdrückt wird.6. Lighting arrangement according to claim 5, characterized in that the length of the further integration rod ( 7 ) is dimensioned such that the structure of the helical pattern is suppressed by repeated reflection on the outer surfaces. 7. Beleuchtungsanordnung nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass die Lichtquelle eine Halogenlampe (1) ist.7. Lighting arrangement according to one of the preceding claims, characterized in that the light source is a halogen lamp ( 1 ).
