Description

  

  Objektiv zur Projektion mehrfarbiger Kinobilder.    Vorliegende Erfindung betrifft ein Objek  tiv zur Projektion mehrfarbiger Kinobilder.  



  Die Zeichnung veranschaulicht ein Aus  führungsbeispiel des Erfindungsgegenstandes.       Fig.    1 stellt eine Aufsicht des Objektives dar,       Fig.    2 ein Längsschnitt durch das Objektiv.  



  In     Fig.    1 und 2 bedeuten<I>a, b, c; d</I> die  Vorderlinsen der vier gleichartigen Teilobjek  tiv e.<I>I,</I>     II,        III,        IV;        a',   <I>b', e', d'</I> bedeuten  die Hinterlinsen dieser Teilobjektive. Hinter  und     Vorlinsen    der Teilobjektive sind je in  einer Fassungshülse e gefasst. Zwischen der       Vorder-und    der     HinterlinsejedesTeilobjektives     ist ein Farbfilter f eingebaut.

   Das Farbfilter       des    Teilobjektives I hat grüne, das des Teil  objektives     1Z    rote, das des Teilobjektives     III          Marie    und das des Teilobjektives<I>IV</I> gelbe  Farbe.

   Die Farben der vier Filter sind also       verschieden.    Die Farbfilter können auch vor       den        Vorderlinsen    der Teilobjektive angebracht       sein.    Die Teilobjektive sind verstellbar an  geordnet; und es sind zur Verstellung am       Objektivgehäuse        g        Mikrometerstellschrauben       <I>h</I> angebracht, welche in<I>i</I> gelenkig mit den  Fassungshülsen der Teilobjektive verbunden  sind.

   Die Verbindung der     Mikrometerstell-          schrauben    mit den Teilobjektiven geschieht  dadurch, dass an     plattenförririgen,    auf den  Fassungshülsen frei aufliegenden Körpern an  geordnete Bolzen in weite     Bohrungen    der  Schrauben     hineinrägen.    Mit den Federzug  vorrichtungen     t    werden die Teilobjektive ge  gen das     Objektivgehäuse        g    gezogen. Dadurch  können die Teilobjektive mit den     Mikronieter-          stellschrauben    h in der für die Projektion der  Kinobilder gewünschten Lage verstellt wer  den.

   Der hintere Teil der Fassungshülsen     P     ist in den     R.illerr,    welche in der Abschluss  platte k eingelassen sind, so gelagert, dass  die 'Peilobjektive mit den     Mikrometerstell-          schrauben    h verstellt werden können. Alle  vier Teilobjektive haben gleiche Linsen. Mit  den     Mikrometerstellschrauben    h sind die Teil  objektive so eingestellt, dass     derer,    optische  Achsen sich in einem Punkte schneiden. In  der durch diesen Punkt gehenden Vertikal  ebene ist die Projektionsfläche anzubringen.

        Dadurch werden die auf einem Kinofilm     mit-          telst        einem    entsprechenden Kinoaufnahme  apparat gemachten über- und nebeneinander  liegenden vier Teilbilder durch die vier Teil  objektive des dargestellten Objektives auf  der     Projektionsfläche    zur Deckung gebracht  und erzeugen auf der Projektionsfläche     eiii     mehrfarbiges Kinobild, das auf den vier Far  ben blau, rot, grün und gelb besteht.



  Lens for projection of multicolored cinema images. The present invention relates to an objective for projecting multicolored cinema images.



  The drawing illustrates an exemplary embodiment of the subject matter of the invention. FIG. 1 shows a top view of the objective, FIG. 2 shows a longitudinal section through the objective.



  In Figs. 1 and 2, <I> denotes a, b, c; d </I> the front lenses of the four similar partial objectives e. <I> I, </I> II, III, IV; a ', <I> b', e ', d' </I> mean the rear lenses of these partial objectives. Behind and fore lenses of the partial objectives are each held in a mount sleeve e. A color filter f is installed between the front and rear lenses of each partial objective.

   The color filter of partial objective I is green, that of part objective 1Z is red, that of part objective III Marie and that of part objective <I> IV </I> is yellow.

   So the colors of the four filters are different. The color filters can also be attached in front of the front lenses of the partial objectives. The partial objectives are adjustable to be arranged; and micrometer adjusting screws <I> h </I> are attached to the lens housing g for adjustment, which are articulated to the mount sleeves of the partial lenses.

   The connection of the micrometer adjusting screws with the partial objectives is done by the fact that on plate-shaped bodies resting freely on the mounting sleeves, arranged bolts protrude into wide holes in the screws. With the spring-loaded devices t, the partial lenses are pulled against the lens housing g. As a result, the partial objectives can be adjusted with the micro-rivet set screws h in the position desired for the projection of the cinema images.

   The rear part of the mount sleeves P is mounted in the R.illerr, which are embedded in the end plate k, in such a way that the bearing objectives can be adjusted with the micrometer adjustment screws h. All four partial objectives have the same lenses. With the micrometer adjusting screws h, the part objectives are set so that their optical axes intersect at one point. The projection surface is to be attached in the vertical plane passing through this point.

        As a result, the four partial images, one above and one next to one another, made on a cinema film by means of a corresponding cinema recording device, are brought into congruence on the projection surface by the four partial objectives of the lens shown and produce a multicolored cinema image on the projection surface that is based on the four colors blue, red, green and yellow.
