Description
Vorrichtung zur gleichzeitigen Erzeugung mehrerer Bilder, insbesondere für Mehrfarbenphotographie. Die Erfindung betrifft eine Vorrichtung zur gleichzeitigen Erzeugung mehrerer Bilder in einer Ebene mit Hilfe von optischen, vor dem Objektiv angebrachten Mitteln. Es sind derartige Vorrichtungen bekannt, bei denen Prismen oder Spiegel zur Herstellung solcher in: eine Ebene fallenden Bilder benutzt werden. Besonders eignen sich derartige Vorrichtungen zur Benutzung für Mehrfarbenphotographien. Die Erfindung unterscheidet sich von diesen bekannten Einrichtungen ähnlicher Art dadurch, daß die brechenden Prismen oder Spiegel eine Pyramide bilden, deren Spitze in der optischen Achse des Objektivs liegt. Vor oder hinter der Pyramide ist eine Abdeckvorrichtung angebracht, welche es verhütet, daß die einzelnen Bilder einander überlappen.Device for the simultaneous generation of several images, in particular for multicolor photography. The invention relates to a device for the simultaneous generation of several images in one plane with the aid of optical means attached in front of the objective. Such devices are known in which prisms or mirrors are used to produce such images falling into a plane. Such devices are particularly suitable for use for multicolor photographs. The invention differs from these known devices of a similar type in that the refracting prisms or mirrors form a pyramid, the tip of which lies in the optical axis of the objective. A covering device is attached in front of or behind the pyramid, which prevents the individual images from overlapping one another.
Die Zeichnungen stel'en Ausführungsformen verschiedener Vorrichtungen dieser Art dar. Es zeigen Abb. i im Schnitt und teilweise in Aufriß eine photographische Kamera nach der Erfindung, Abb. 2 eine Draufsicht auf das pyramidenförmige Prisma, dessen Flächen nach den Ecken abfallen, Abb. ; schematisch die Anbringung von Spiegeln bei einer anderen Ausführungsform, Abb. 4. eine Abdeckvorrichtung in Vorderansicht, Abb. 5 eine Abblendvorrichtung, von vorn gesehen, und Abb.6 einen Schnitt durch diese Vorrichtung nach 9-9 der Abb. 5.The drawings represent embodiments of various devices of this kind. Fig. i shows a photographic section and partly in elevation Camera according to the invention, Fig. 2 is a plan view of the pyramidal prism, the surfaces of which slope towards the corners, fig.; schematically the attachment of mirrors in another embodiment, Fig. 4, a cover device in front view, Fig. 5 shows a masking device, seen from the front, and Fig. 6 shows a section through this device according to 9-9 of Fig. 5.
Die photographische Kamera i mit einem Auszugbalg 7 trägt ein Objektiv 2 mit einem Vorbau 3, in welchem ein Prisma 4. angebracht ist. Am anderen Ende befindet , ich eine Mattscheibe 5 und der Träger 6 der empfindlichen Schicht.The photographic camera i with a pull-out bellows 7 carries an objective 2 with a stem 3 in which a prism 4. is attached. Located at the other end , I have a focusing screen 5 and the carrier 6 of the sensitive layer.
Das im wesentlichen rechteckige, im Brennpunkt vor dem Objektiv angebrachte Prisma .1 hat vier gegen die Ecken geneigte Flächen 8, 9, io und i i, die in einem Punkt aneinander anstoßen, welcher in der Objektivachse 25 liegt. Die Flächen 8, 9, 1o und t i liegen so zueinander, daß von einem Gegenstand 12 auf dem Träger der lichtempfindlichen Schicht vier gleich große Bilder i.;" 1:1, 15 und 16 erzeugt werden, die mit Bezug auf die Achse 25 symmetrisch liegen. Dazu ist nur eine einzige Aufnahme notwendig. Befindet sich das Prisma in der angegebenen Lage zur Linse 2, so braucht diese Lage nicht geändert zu werden, auch wenn das Objektiv selbst entsprechend der Entfernung des aufzunehmenden Gegenstandes eingestellt wird.The essentially rectangular one that is attached at the focal point in front of the lens Prism .1 has four surfaces inclined towards the corners 8, 9, io and i i, which are in one Butt against each other which lies in the objective axis 25. The surfaces 8, 9, 1o and t i are to each other that of an object 12 on the carrier light-sensitive layer produces four images of the same size i .; "1: 1, 15 and 16 which are symmetrical with respect to the axis 25. There is only one for this Recording necessary. If the prism is in the specified position to lens 2, so this position does not need to be changed, even if the lens itself accordingly the distance of the object to be recorded is set.
An Stelle des pyramidenförmigen Prismenblocks können auch vor dem Objektiv geneigte Spiegel 17 so angebracht sein, die eine Pyramide bilden, deren Spitze in der optischen Achse des Objektivs liegt, siehe Abb. 3. Auch in diesem Falle entstehen auf dem Träger der lichtempfindlichen Schicht vier gleiche Bilder j3, 14, 15 und 16 desselben Gegenstandes 12 wie mit dem. Prismenblock.Instead of the pyramid-shaped prism block, you can also use the Objectively inclined mirror 17 be attached to form a pyramid, whose Tip lies in the optical axis of the lens, see Fig. 3. Also in this one Trap, four identical images are formed on the support of the photosensitive layer j3, 14, 15 and 16 of the same item 12 as with the. Prism block.
`Wird ein einziges Prisma benutzt, d. h. ein. Prisma, das nicht etwa aus vier Teilen zusammengesetzt ist, so ist .es ratsam, eine Abdeckvorrichtung zu verwenden. Diese Vorrichtung 18 (Abb. ¢) hat die lichtdurchlässigen Teile i 9 und die nichtdurchlässigen Teile 2o. Dadurch wird verhindert, daß sich die verschiedenen Bilder überlappen. Der Schirm kann entweder vor oder hinter dem Prisma .1 senkrecht zur Achse der Linse 2 eingesetzt werden.`If a single prism is used, i. H. a. Prism, not that is composed of four parts, so it is advisable to use a covering device use. This device 18 (Fig. ¢) has the translucent parts i 9 and the impermeable parts 2o. This prevents the different Overlap images. The screen can either be in front of or behind the prism .1 vertically to the axis of the lens 2 are used.
Um bei der Aufnahme seitlich einfallende Lichtstrahlen abzuschneiden, so daß möglichst nur parallel zur Achse einfallende Lichtstrahlen zur Wirkung kommen, ist eine Blendvorrichtung 21 (Abb.5, 6) angebracht. Diese hat Teilwände 22, 23 und wird zweckmäßig vor dem Prisma 2 aufgestellt; dabei wird die Lage des Prismas so gewählt, daß eine fiberlappung der einzelnen Bilder verhindert wird.To cut off laterally incident light rays when recording, so that if possible only rays of light incident parallel to the axis come into effect, a masking device 21 (Fig.5, 6) is attached. This has part walls 22, 23 and is expediently set up in front of the prism 2; the position of the prism becomes like this chosen so that an overlapping of the individual images is prevented.
