Description
Mehrfarberiadrtähmekamera Die Erfindung betrifft eine Mehrfarbenaufnahmekamera mit einem Strahlenteiler, der mittels einzelner Spiegel das vom Objektiv kommende Licht aufteilt und den einzelnen Teilbildebenen zuleitet. Aus praktischen Gründen ist es bekanntlich zu empfehlen, Farbenkameras größeren Bildformats des Gewichts halber statt mit Prismen nur mit Spiegeln auszustatten. Die mechanische Spiegelbefestigung und ihre gegenseitige Anordnung verursachen Schwierigkeiten. Diese Schwierigkeiten sollen durch die vorliegende Erfindung dadurch behoben werden, daß sämtliche Spiegel an nach außen frei liegenden Flächen, und zwar möglichst an Außenflächen, eines entweder aus einem Ganzen bestehenden oder aus mehreren Teilen zu einer festen Einheit zusammengesetzten, auch das Objektiv aufnehmenden Gehäuses angebracht sind. Sämtliche optischen Teile sind somit an einem festen Körper festgelegt, an dem leicht Paßflächen für die einzelnen Teile gebildet werden können. Die spiegeltragenden Flächen stellen, obwohl sie teilweise Innenflächen sind, für die Bearbeitung Außenflächen dar. Soll das Gehäuse ein Ganzes bilden, so ist es zweckmäßig im Spritz- oder Preßgußverfahren herzustellen, worauf man bekanntlich auch sonst schon im Kamerabau gekommen ist. Die Spiegel können dann ohne großes Nacharbeiten darauf befestigt werden.Multi-color rotating camera The invention relates to a multi-color shooting camera with a beam splitter, which by means of individual mirrors the coming from the lens Divides light and directs it to the individual sub-image levels. Because of practical reasons It is well known to recommend color cameras of larger image size of the weight just to equip them with mirrors instead of prisms. The mechanical mirror mounting and their mutual arrangement causes difficulties. These difficulties are to be solved by the present invention in that all mirrors on surfaces exposed to the outside, and if possible on outer surfaces, one either consisting of a whole or of several parts to form a solid unit composite, also the lens receiving housing are attached. All optical parts are thus fixed to a solid body on which easily mating surfaces can be formed for the individual parts. Place the mirror-bearing surfaces, although some of them are inner surfaces, they are outer surfaces for machining. Should the housing form a whole, so it is expedient in the injection or pressure molding process to produce what, as is well known, has already come about in camera construction. The mirrors can then be attached to it without any major reworking.
Auf der Zeichnung ist der Gegenstand der Erfindung in einem Ausführungsbeispiel schematisch dargestellt. Dabei zeigt Abb. r das Gehäuse in Richtung auf die Objektivöffnung hin von außen gesehen, während Abb. a den Gehäusekörper in einer Ansicht von unten und Abb.3 in einer solchen von oben darstellt.In the drawing, the subject of the invention is in one embodiment shown schematically. Fig. R shows the housing in the direction of the lens opening seen from the outside, while Fig. a shows the housing body in a view from below and Fig.3 shows such a view from above.
Hinter der Objektivöffnung d sind nach Abb.3 auf säen Flächen a ', b' und c' Spiegel aufgelegt, die das vom Objektiv kommende Lichtbüschel in drei Teile zerlegen und nach den freien Öffnungen a, b und c werfen, und zwar von a nach a'; von b nach b' und von c nach c'. . Vor den Öffnungen a, b, c sind auf die Außenwände des Gehäuses mit ihrer spiegelnden Fläche nach innen gekehrte Spiegel aufgelegt, die das Licht nach drei hier in einer Ebene gelegenen Schichtträgerfeldern für drei Farbauszüge gelangen lassen.'Levels are d behind the lens aperture according to Fig.3 to sow surfaces a', b 'and c hook, which divide the light coming from the objective light bundle into three parts and c throw at the free openings of a, b and, from a to a '; from b to b ' and from c to c'. . In front of the openings a, b, c , mirrors facing inward are placed on the outer walls of the housing with their reflective surface, which allow the light to reach three layer carrier fields for three color separations, which are here in one plane.
