Abstract
Endoskopoptik (1) mit Linsen (5.1, 5.2, 5.3), die in einem elastisch umfangsfedernden, geschlitzten Rohr (2) verschiebungssicher geklemmt sind, dadurch gekennzeichnet, dass der Innendurchmesser des geschlitzten Rohres (2) in Ruhe größer ist als der Durchmesser der Linsen (5.1, 5.2, 5.3), und dass die Anordnung von geschlitztem Rohr (2) und Linsen (5.1, 5.2, 5.3) mit einem Schrumpfschlauch (7) umgeben ist.Endoscope optics (1) with lenses (5.1, 5.2, 5.3), which are clamped securely against displacement in an elastically circumferentially resilient, slotted tube (2), characterized in that the inner diameter of the slotted tube (2) is greater at rest than the diameter of the lenses (5.1, 5.2, 5.3), and that the arrangement of slotted tube (2) and lenses (5.1, 5.2, 5.3) with a shrink tube (7) is surrounded.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine gattungsgemäße Endoskopoptik zu schaffen, bei der die Linsen einfacher justierbar sind.The object of the present invention is to provide a generic endoscope optics, in which the lenses are easier to adjust.
Erfindungsgemäß ist der Innendurchmesser des Rohres in Ruhe größer als der Linsendurchmesser. Die Linsen können also in das Rohr eingelegt und dort leicht und ohne störende Klemmwirkung verschoben und dadurch justiert werden. Das Klemmen geschieht hier durch ein zusätzliches Bauteil, nämlich einen die gesamte aus Rohr und Linsen bestehende Anordnung umschließenden Schrumpfschlauch, der die Linsen gegen das Rohr presst und das elastisch umfangsfedernde Rohr unter Verkleinerung des Schlitzes zusammenpresst. Da ein Schrumpfschlauch üblicherweise durch Erwärmung geschrumpft wird, können noch mit um die Anordnung gelegtem Schrumpfschlauch letzte Justierarbeiten an den Linsen vorgenommen werden, bis dann durch Erwärmung die Schrumpfung durchgeführt wird. Durch diese Konstruktion werden die Möglichkeiten zur Feinjustierung der Linsen wesentlich verbessert und vereinfacht, da insbesondere bei der Justierung keine Kräfte zum Offenhalten des Schlitzes erforderlich sind.According to the invention, the inner diameter of the tube at rest is greater than the lens diameter. The lenses can therefore be inserted into the tube and moved there easily and without disturbing clamping action and thereby adjusted. Clamping is done here by an additional component, namely a shrink tube which encloses the entire tube and lens assembly, which presses the lenses against the tube and compresses the elastically circumferentially resilient tube while reducing the slit. Since a shrink tube is usually shrunk by heating, can still be made with adjusted to the arrangement shrink tubing last adjustments to the lenses until the shrinkage is then carried out by heating. By this construction, the possibilities for fine adjustment of the lenses are substantially improved and simplified, since in particular no forces are required to hold the slot open during the adjustment.
Vorteilhafte Schlitzabmessungen ergeben sich aus den Ansprüchen 2–4.Advantageous slot dimensions emerge from the claims 2-4.
