Description

Die Erfindung betrifft ein Tubuslinsensystem mit Kompensatoren für Polarisationsmikroskope.The invention relates to a tube lens system with compensators for Polarizing microscopes.

Es ist bekannt, bei Polarisationsmikroskopen verschiedene Kompensatortypen zwischen Objektiv und Okular auswechselbar anzuordnen. Wenn diese Kompensatoren im konvergenten Strahlengang angeordnet sind, dann ergeben sich mehrere Nachteile. So sind beim Ein- und Ausschalten bzw. Kippen der Kompensatoren geringer Nachfokussierungen des Bildes notwendig. Außerdem wandert ein auf Fadenkreuzmitte eingestellter Objektpunkt beim Kippen des Kompensators seitlich aus. Ferner muß bei genauen Messungen die Parallelversetzung des Interferenzstreifensystems beim Kippen des Kompensators durch Korrektur der Kompensatorfunktionen berücksichtigt werden.It is known to use different types of compensators in polarizing microscopes to be arranged interchangeably between objective and eyepiece. If these expansion joints are arranged in the convergent beam path, then there are several disadvantages. This means that when the compensators are switched on and off or tilted, there is less refocusing of the picture necessary. In addition, an object point set to the center of the crosshair moves sideways when tilting the expansion joint. Furthermore, for precise measurements, the Parallel displacement of the interference fringe system when tilting the compensator Correction of the compensator functions must be taken into account.

Diese Nachteile entfallen dann, wenn die Kompensatoren im Parallelstrahlengang angeordnet sind. Es ist dazu schon vorgeschlagen worden, die Kompensatoren zwischen die beiden Glieder des Analysatorsystems des Polarisationsmikroskops einzusetzen, zwischen denen ein Parallelstrahlengang besteht. Bei modernen Mikroskopen sind die Analysatorsysteme jedoch inner- bzw. oberhalb eines festen Stativteils angeordnet, oberhalb dessen verschiedene Beobachtungstuben auswechselbar vorgesehen sind. Unterhalb dieses Stativteils sind in bekannter Weise verschiedene Objektivwechseleinrichtungen auswechselbar vorgesehen. Das führt jedoch dazu, daß die Analysatorsysteme verhältnismäßig weit von den Objektivpupillen entfernt liegen. Da die Kompensatoren aber im allgemeinen sehr kleine freie Durchgänge besitzen, erfolgt beim Einsetzen dieser Kompensatoren zwischen die Teilglieder des Analysatorsystems eine sehr starke Vignettierung. Dieser Nachteil läßt sich erfindungsgemäß dadurch beseitigen, daß im objektivnahen Teil. des' Mikroskoptubus zwei Linsenglieder angeordnet sind, zwischen denen paralleler Strahlengang besteht, und daß zwischen diese beiden Linsenglieder wahlweise verschiedene Kompensatoren einschiebbar oder einschwenkbar angeordnet sind.These disadvantages do not apply if the compensators are in the parallel beam path are arranged. It has already been proposed to place the expansion joints between to use the two links of the analyzer system of the polarizing microscope, between which there is a parallel beam path. With modern microscopes they are Analyzer systems, however, arranged inside or above a fixed part of the stand, above which various observation tubes are provided interchangeably. Below this stand part are various lens changing devices in a known manner interchangeable provided. However, this means that the analyzer systems are proportionate are far from the lens pupils. Since the expansion joints but in general have very small free passages when inserting these expansion joints a very strong vignetting between the sub-elements of the analyzer system. This Disadvantage can be eliminated according to the invention in that in the part close to the lens. des' microscope tube two lens elements are arranged, between which parallel There is a beam path, and that optionally different between these two lens members Compensators can be pushed in or swiveled in.

In der Zeichnung ist schematisch ein Mikroskop mit einer Anordnung nach der Erfindung dargestellt. An dem Stativ 1 des Mikroskops mit dem Objekttisch 2 ist ein Objektivträgerstück 3 mit einem Objektivrevolver 4 und den Objektiven 5 und 6 angeordnet. Auf der Oberseite des Stativs sind das Analysatorsystem 7, ein Beobachtungstubus 8 und ein Anschlußstutzen 9 für eine mikrophotographische Einrichtung vorgesehen. In dem Objektivträgerstück 3 sind zwei Linsenglieder 10 angeordnet, zwischen dessen Teillinsen 11 bzw. 12 paralleler Strahlengang besteht. Zwischen den Teillinsen 11 und 12 ist der Kompensator 13 vorgesehen.In the drawing, a microscope with an arrangement according to the invention is shown schematically. On the stand 1 of the microscope with the object table 2, an objective carrier piece 3 with an objective nosepiece 4 and the objectives 5 and 6 is arranged. The analyzer system 7, an observation tube 8 and a connection piece 9 for a microphotographic device are provided on the upper side of the stand. In the lens support piece 3, two lens members 10 are arranged, between whose partial lenses 11 and 12 there is a parallel beam path. The compensator 13 is provided between the partial lenses 11 and 12.
