Description

Einrichtung zur Verhinderung störender Nebenbilder in Farbenkameras Die Erfindung betrifft .ein Lamellensysten zur Verhinderung der störenden Doppelbilder, wie sie .oft bei der Herstellung. von Zwei-oder Drieifarbenaufnahmen änit Hilfe von Spiegeln oder Prismen eintreuen.Device to prevent disruptive secondary images in color cameras The invention relates to .ein lamella system to prevent the annoying double images, like them .often in the production. of two- or three-color photos with help from mirrors or prisms.

In der Zeichnung stellen 3, q., 6; 7 d"ie Spiegel, 2, 5, 8 .die Objektive dar.In the drawing represent 3, q., 6; 7 the mirrors, 2, 5, 8. The lenses represent.

D'as vom Objekt einfallende Licht trifft in bekannter Weise auf einen durchlässiglen obersten Spiegel 3, von dem gemäß dem Prozentsatz der Versilberung ein Teil des Lichtes auf den darunter gelagerten Spiegel6 hindurchgelassen, der andere Teil. des auffallenden Lichtes seitlich reflektiert wird und auf die voll versilberte Fläche des Spiegels q. trifft. In ,ähnlicher Weise verlaufen alle übrigen .einfaulenden Lichtstrahlen. Es ist nun nicht zu verhindern, daß außer den für das Bild bestimmten mittleeren Lichtstrahlen, die über die Spiegel in das. Objektitv gelanglen, auch noch mehr seitlich andere Lichtstrahlen durch den obersten Spiegel einfallen und unter Umgehung dies voll versilberten. Spiegels unmittelbar in das betreffende Objektiv gelangen, so daß in störender Weise Nebenbilder entstielen. Um diesen Übelstand zu unterdrücken, werden ungefähr parallel zum mittleren Strahlenbündel in den Strahlengang Gruppen von Lamellen 9 und r o eingeschaltet, wie in der Zeichnung dargestellt. Diese dünnwandigen Lamellen sperren die unmittelbar einfallenden Strahlen der Breite nach ab, ohne daß die im Winkel von 9o° reflektierten Strahlen irgendwie behindert werden. Es genügen Lamellen von hauchdünner `Feinheit. Zweckmäßig kann man dies;e_ Lamellen als kleine längliche Stäb:chen aus beliebigem Material, :etwa Metall oder Papier, herstellen.The light falling from the object hits you in a known way transparent top mirror 3, of which according to the percentage of silver plating some of the light is allowed to pass onto the mirror 6 below, which other part. of the incident light is reflected laterally and on the full silvered surface of the mirror q. meets. All the others proceed in a similar manner .doting rays of light. It is now unavoidable that besides those for that Image certain medium rays of light, which through the mirror into the. Objectitv succeeded, even more laterally other rays of light through the top mirror come up and bypassing this fully silver-plated. Mirror directly into the relevant objective so that secondary images stalked in a disturbing manner. To suppress this inconvenience, be approximately parallel to the central beam in the beam path groups of lamellas 9 and r o switched on, as in the drawing shown. These thin-walled lamellas block the directly incident rays in width, without the rays reflected at an angle of 90 ° in any way be hindered. It is sufficient to have lamellas of extremely fine fineness. Appropriate can one dies; e_ lamellae as small elongated rods made of any material,: for example Metal or paper.
