Description
Zur Erzielung verschiedener Vergrößerungen in einem Fernrohr bietet die Okularwechslung die konstruktiv einfachste, meist ausführbare und meist auch befriedigende Lösung. Die Öbjektivwechslung dagegen findet seltener und nur dann Anwendung, wenn man auf die Erhöhung des Auflösungsvermögens nicht verzichten will. Die Gründe für die seltenere Anwendung der Öbjektivwechslung sind inTo achieve different magnifications in one telescope, the eyepiece change offers the structurally simplest, mostly feasible and mostly also satisfactory solution. the Objective change, on the other hand, is less common and only used when one is on the increase does not want to do without resolving power. The reasons for the rarer Use of lens changes are in
lo t erhöhten mechanisch-konstruktiven Schwierigkeiten, zu suchen, bei denen entweder Vorsprünge und Ansätze, welche das Volumen vergrößern und das Aussehen des Instruments beeinträchtigen, nicht zu vermeiden sind oder lo t increased to search mechanical constructive difficulties, in which either the projections and approaches that increase the volume and detract from the appearance of the instrument, can not be avoided or
1S zur Erhaltung der Bildebene weitere optische Hilfsmiitel hinzugeschaltet werden müssen. 1 S further optical aids must be added to maintain the image plane.
Bei den bisher bekannten Einrichtungen für den Öbjektivvergrößerungswechsel werden die Objektive meist durch eine Drehbewegung um eine ' gemeinsame Achse aus der optischen Achse des Okulars herausverlegt. Hiervon unterscheidet sich die vorliegende Erfindung im wesentlichen dadurch, daß die ausklappbaren Objektive um getrennte, zur optischenIn the previously known devices for changing the lens magnification, the Lenses usually by a rotary movement around a 'common axis from the optical Axis of the eyepiece moved out. The present invention differs from this essentially in that the fold-out lenses to separate, to the optical
2S Achse senkrecht stehende Achsen schwenkbar und zwangläufig derart miteinander verbunden sind, daß das eine eingeschaltet ist, wenn das ,andere ausgeschaltet ist. Bei Doppelfernrohren wird dabei die Anordnung so getroffen, daß die Objektive gleicher Brennweite gleichzeitig und um gemeinsame Achsen ein- und ausgeschaltet werden. 2 S axis vertical axes are pivotable and inevitably connected to one another in such a way that one is switched on when the other is switched off. In the case of double telescopes, the arrangement is made so that the lenses of the same focal length are switched on and off simultaneously and around common axes.
Indem sich die ausgeschwenkten Objektive bei Einzelfernrohren an die innere Rohrwand, bei Doppelferngläsern zwischen die beiden Fernrohre legen, bleibt den Instrumenten die glatte von Vorsprüngen und Ansätzen freie Form erhalten. Hierzu tritt noch der weitere, dem beobachtenden Auge außerordentlich wohltuende Vorzug hinzu, daß sich der Vergröße- 4< rungswechsel nicht sprunghaft vollzieht, d. h. durch einen Moment völliger Verdeckung des Gesichtsfeldes unterbrochen ist, sondern daß das Bild über mehr und mehr zunehmende Unscharfe und Verschwommenheit wieder in 4; dje Schärfe bei veränderter Vergrößerung übergeht. As the swiveled-out objectives of single telescopes are attached to the inner tube wall, place between the two telescopes in the case of binoculars, the instruments remain the get smooth of projections and approaches free form. To this comes the further one, To the observing eye an extraordinarily beneficial advantage is that the enlargement is possible does not make a sudden change in direction, d. H. by a moment of complete obscuration of the The visual field is interrupted, but that the image is increasing more and more Blurring and blurring again in 4; The sharpness passes over when the magnification is changed.
Die Zeichnung veranschaulicht, wie bei einem Doppelfernrohr die beidenObjektive fx und f2 etwa durch eine Pleuelverbinduhg auf gekreuz- 5< ten Fassungen so angebracht und gekuppelt sind, daß sich bei Gebrauchsstellung des einen Objektivs das andere in Ruhelage befindet.The drawing illustrates how the two objectives f x and f 2 in a binocular telescope are attached and coupled, for example by a connecting rod connection on crossed mounts, in such a way that when one objective is in use the other is at rest.
