Description

Die Erfindung betrifft ein optisches System zur Aufnahme und Wiedergabe von Linsenrasterfilmen mit Hilfe einer vor dem Film befindlichen KoHimatorlinse, das gleichzeitig hinsichtlich der von der Kollimatorlinse verursachten Abbildungsfehler korrigiert ist, da diese Fehler zu Farbverfälschungen Anlaß geben. Die Neukonstruktion besonderer, den Verhältnissen der Kollimatorlinse angepaßter Objektive ist aber mit einem hohen Aufwand an Zeit und Kosten verbunden.The invention relates to an optical system for recording and reproducing lenticular lenticular films with the help of a KoHimatorlens located in front of the film, which at the same time with respect to those caused by the collimator lens Image errors are corrected, since these errors give rise to color distortions give. The redesign of special ones adapted to the conditions of the collimator lens Lenses are, however, associated with a high expenditure of time and money.

Erfindungsgemäß wird dieser Nachteil dadurch behoben, daß bei Verwendung eines an sich bekannten, aus einem sammelnden Bestandteil und einem vor diesem angeordneten, die Gesamtbrennweite des Systems verkürzenden zerstreuenden Bestandteil bestehenden optischen Systems die Beseitigung der durch die Kollimatorlinse verursachten Abbiiso dungsfehler allein durch entsprechende Ausbildung der zerstreuenden Vorsatzlinse bewirkt wird.According to the invention, this disadvantage is eliminated in that when using a known per se, consisting of a collecting component and a component arranged in front of it, the existing diffusing component shortens the total focal length of the system optical system eliminates the Abbiiso caused by the collimator lens education errors caused solely by appropriate training of the divergent ancillary lens will.

Auf diese Weise ist es möglich, bereits vorhandene photographische Objektive zu verwenden, wodurch die Kosten, die mit dem Bau eines gänzlich neuen Objektivs verbunden sind, gespart werden.In this way it is possible to use existing photographic lenses, thereby saving the costs associated with building a brand new lens.

Die Anordnung der einzelnen Bauglieder des Gesamtsystems im Strahlengang zeigt die Zeichnung. ·The arrangement of the individual components of the overall system in the beam path shows the Drawing. ·

Vor dem Linsenrasterfilm g ist die KoHimatorlinse c angeordnet. Mit O ist das für sich auskorrigierte übliche Objektiv bezeichnet, vor dem sich eine negative Zusatzlinse N befindet.The KoHimator lens c is arranged in front of the lenticular lens film g. The usual objective which has been corrected for itself and in front of which there is a negative additional lens N is designated with O.

Gemäß der Erfindung wird der durch die Kollimatorlinse notwendig werdende zusätzliche Fehlerausgleich allein an der negativen Zusatzlinse 'N vorgenommen, so daß das Objektiv O seine ursprüngliche Korrektion behält und auch ohne >Köllimatorlinse verwendbar bleibt.According to the invention, the additional compensation for errors made necessary by the collimator lens is carried out solely on the negative additional lens' N , so that the objective O retains its original correction and can also be used without the collimator lens.
