Description
Prismendoppelfernrohr. Gegenstand der Erfindung ist ein Prismendoppelfernrohr, das hinsichtlich seiner Abmessungen und seines Gewichtes den Ansprüchen genügen soll, die an ein dauerhaftes Theaterglas mit hohen optischen Eigenschaften gestellt werden können. Es hat, wie bereits bekannte Prismendoppelfernrahre. zwei mit Okularen versehene Prismenpaare, die um die Objektivachsen drehbar an einem stegartigen Gestell, das die Objektive hält, gelagert sind. Das neue Fernrohr unterscheidet sich von den älteren durch eine besondere Art der Lagerung der Prismenpaare an dem Objektivhalter, wodurch es in der Sehrichtung verkürzt wird. Der Schwerpunkt der Teile liegt in der Nähe des Ob jektivhalters, an dem das Gerät beim Gebrauch angefaBt wird. Die besondere Lagerung kennzeichnet sich dadurch, daB die Prismen auf beiden Seiten ihrer gegen den Objektivhalter drehbaren Trägerplatten so angeordnet sind, daß sich die Schutzgehäuse der Okularprismen gegen eine Längsseite des Objektivhalters legen, wenn die Okulare auf den kleinsten Abstand zusammengeführt werden.Prism binoculars. The invention relates to a prism binoculars, which meet the requirements in terms of its dimensions and weight that should be placed on a durable theater glass with high optical properties can be. It has, like already known prism double telescopes. two with eyepieces provided pairs of prisms, which can be rotated around the objective axes on a bridge-like frame, that holds the lenses are stored. The new telescope differs from the older by a special way of mounting the prism pairs on the lens holder, whereby it is shortened in the direction of vision. The focus of the parts is in the vicinity of the lens holder by which the device is grasped during use. the special storage is characterized by the fact that the prisms are on both sides their rotatable against the lens holder support plates are arranged so that place the protective housing of the eyepiece prisms against one of the long sides of the lens holder, when the eyepieces are brought together to the smallest distance.
Der Erfindungsgegenstand ist in der Zeichnung beispielsweise veranschaulicht. Die Abb. i und z zeigen ihn von der Okularseite, und zwar gebrauchsfertig in Abb. i und für die Verwahrung in einem Behälter zusammengeklappt in Abb. z. Die Abb. 3 zeigt das zusammengeklappte Gerät von der einen Seite. Der stegartige Objektivhalter ist mit a, die Trägerplatten der optischen Systeme sind mit hl, b2, die Objektive mit c,., c2, die Okulare mit dl, d2, die Objektnvprismen mit e1, e2, die Okularprismen mit f,, f2 bezeichnet.The subject matter of the invention is illustrated in the drawing, for example. Figs. I and z show it from the eyepiece side, ready for use in Fig. i and folded for storage in a container in Fig. z. Fig. 3 shows the folded device from one side. The bridge-like lens holder is marked with a, the carrier plates of the optical systems are marked with hl, b2, the objectives with c,., c2, the eyepieces with dl, d2, the object prisms with e1, e2, the eyepiece prisms denoted by f ,, f2.
