Description

Istota wynalazku polegal na tein, ze ru¬ chome, stosunkowo wielkie zwierciadlo rzu¬ ca promienie swietlne na trzy poza niem jedno za drugiem ustawione ruchome i stop¬ niowo coraz mniejsze zwierciadla do ob¬ iektywów. Wskutek malych rozmiarów ob¬ razów kinowych odleglosci ogniskowe sa krótkie, co powoduje te wade, ze ramki zwaerciadlowe, wzglednie paski osrebrzone doznaja wspólnego odfotografowiania. Zwier¬ ciadla ruchome na wszystkie strony nalezy umiesbic bezposrednio' przed sciczewkami objektywów. Aby osiagnac wielki kat obra¬ zowy, nalezy zastosowac bardzo wielkie zwierciadlo. Zwierciadla db objektywów sa stopniowo coraz mniejsze, tak, ze najwyzej umieszczone wieksze jest, anizeli srodko¬ we, a srodkowe wieksze od nastepnego.Przez to stopniowanie unika sie wspólnego odfotografowamia obramowania zwierciadel oraiz osiaga sie równoczesnie powiekszenia pola obnaizu. Gdyby, np. zwierciadlo przed najwyzej umieszczonym objebtywem bylo równie tak wielkie, jak wlielkile Ewierciiadlo, to odwrotna strona jego obramowania by¬ laby odtworzona przez pierwszy objektyw.To samo dotyczy reszty objektywów i zwier¬ ciadel.Aby uniknac tworzenia sie podwójnych obrazów, zastosowuje sie dla najwyzej i srednio umieszczonego olbjektywu klinowe plytki.Rozdiziial swiatla bez oslony objektywu m brzenie dolnego kata plytek srodkowego zwierciadla. ¦4Przedstawiony na rysunku przyklad przedstawia wielkie zwierciadlo 1, zwiercia¬ dla przed objektywatmi 2, 3, 4 i objektywy 5. Wielkie zwierciadlo jako tez zwierciadlafr przed objektywami sa umieszczone rucho- cCmo, a| mianowicia osadzone jest kazde, np. ^ ! w raii^^:,<^iQ^iiGh 7, przy):jzem rama ob¬ raca sie okolo czopa 6 (fig. 3). Zwierciadla umieszczone sa bezposrednio przed obiek¬ tywami, aby w polaczeniu z wielkiem zwier¬ ciadlem osiagnac mozliwie najwieksize pole obrazu takze dla dolnego cbjektywu. PLThe essence of the invention consisted in the fact that a movable, relatively large mirror projects light beams three beyond them, one behind the other, positioned movable and gradually smaller and smaller mirrors for lenses. Due to the small size of the cinematic images, the focal lengths are short, which causes the drawback that the fringe frames, or the silvered stripes, share a common undo-photography. Movable mirrors in all directions should be placed directly in front of the lens caps. To achieve a great angle, a very large mirror must be used. Objective mirrors are progressively smaller, so that the highest position is larger than the middle one, and the middle one is larger than the next one. Thus, the gradation avoids the common imaging of the fringes of the mirror glasses and the simultaneous enlargement of the field of exposure is achieved. For example, if the mirror in front of the uppermost lens were as large as the large mirror image, then the reverse side of its border would be reproduced by the first lens. The same is true for the rest of the objectives and the mirror. To avoid the formation of double images, the following applies: for the highest and middle position of the lens, wedge-shaped plates. It radiated light without the lens cover m reflecting the lower angle of the plates of the middle mirror. ¦4The example shown in the figure shows a large mirror 1, the mirrors in front of the objects 2, 3, 4 and the objective 5. The large mirror as also a mirror in front of the lenses is placed on the moveCmo, and | each appointment is embedded, e.g. ^! in relation to the spigot 6 (FIG. 3). The frame rotates around the spigot 6 (FIG. 3). The mirrors are placed directly in front of the lenses in order to achieve the largest possible image field in combination with the large mirror also for the lower lens. PL
