Description
Nachtschußgerät. Zusatz zum Patent 313ro6. In dem Patent 313io6 ist klargelegt, daß es von großer Wichtigkeit ist, in der Lampenebene ein aufrechtes Bild der Gegend zu entwerfen. Die Erfindung bezieht sich dabei auf eine Bildumkehrung mittels Linsenumkehrsystems, wobei die gleichzeitige optische Verkürzung berücksichtigt ist.Night gun. Addition to patent 313ro6. In the 313io6 patent is made it clear that it is of great importance to have an upright position in the lamp plane Design image of the area. The invention relates to an image reversal by means of a lens erecting system, taking into account the simultaneous optical shortening is.
Die Forderung der Bildumkehrung läßt sich aber auch durch Einführung eines Prismen- oder Spiegelumkehrsystems erreichen, das vor dem Objektiv oder zwischen Objek- tiv und Lampe angebracht werden kann. Im letzteren Falle bewirkt es gleichzeitig, daß .die mechanische Länge ,des Gerätes A kleiner wird als die Objektivbrennweite (Abb. i und z).The requirement of image reversal can also be achieved by introducing a prism or mirror reversal system that can be attached in front of the lens or between the lens and the lamp. In the latter case, it also has the effect that the mechanical length of the device A is smaller than the focal length of the lens (Figs. I and z).
Es kann in besonderen Fällen an das Gerät die Forderung eines ausnehmend kleinen Baues gestellt werden. Diese Forderung läßt sich erfüllen, wenn man zum verkürzenden Umkehrsystem noch ein Nagativsystem c einschaltet, wie es in der Zeichnung (Abb. i und z) angedeutet ist. Ein anderer Fall der Verwendung des Umkehrsystems ist in Abb. 3 dargestellt.' . Hier geht das zerstreute Licht nicht durch das Objektiv, sondern am Ob- jektiv vorbei, was gleichzeitig den Vorteil der Verwendungsmöglichkeit eines sehr hellen Spiegels hat, da das Licht nicht durch das Objektiv gehen muß, die Spiegelgröße also nicht beschränkt ist. In Abb. q. ist eine zweite Anordnung gegeben, bei welcher das zerstreute Licht nicht durch das Objektiv geht.In special cases, the device can be required to have an exceptionally small structure. This requirement can be met if a negative system c is switched on in addition to the shortened inversion system, as indicated in the drawing (Figs. I and z). Another case of using the inversion system is shown in Fig. 3. . Here the scattered light does not pass through the lens, but the lens over, what has the same advantage of the possible use of a very bright mirror because the light does not pass through the lens, the mirror size is therefore not limited. In Fig.q. a second arrangement is given in which the scattered light does not pass through the lens.
Zur Erzielung eines aufrechten Bildes in der Bildebene muß die Ablenkung b (Abb. i) durch ein Pentaprisma, die Ablenkung b1 durch ein Dachprisma erfolgen. Man kann darauf verzichten, da man durch die punktiert angedeutete Vorrichtung (Abb. q.) infolge der weit nach vorn gegen a gesuchten Bildebene bei einwandfreier Lage des Auges einschießen kann.To achieve an upright image in the image plane, the deflection b (Fig. i) by a pentaprism, the deflection b1 by a roof prism. You can do without it, because the device indicated by dotted lines (Fig. q.) as a result of the image plane sought far forward towards a in a perfect position of the eye can shoot.
