Description
Optisches System zur Besichtigung von Körperhöhlen und Körperröhren sowie zum Prüfen von technischen Gegenständen Es sind Instrumente der angewandten medizinischen Optik bekannt, bei. denen. eine mehrfache Ablenkung der optischen Achse durch in den Strahlengang eingeschaltete reflektierende Prismen b!ewixkt wird.Optical system for viewing body cavities and body tubes as well as for testing technical objects there are instruments of the applied known medical optics. those. a multiple deflection of the optical Axis b! Ewixkt by switched on in the beam path reflecting prisms.
Von diesen bekannten Instrumenten unterscheidet sich das vorliegende- optische System dadurch, daß zum parallelen Vers-e.tzen der .optischen. Längsachse an Ste11e reflektierender Prismen .dioptrische Mittel zur Verwendung gelangen.The present- optical system in that for the parallel verse-etching of the .optischen. Longitudinal axis Dioptric means come to use on ste11e reflective prisms.
Die Benutzung solcher dioptrischer Mittel an sich ist zwar auch schon mehrfach. bekannt geworden. Gegenüber diesen bisher verwendeten dioptrischen Mitteln handelt es sich beim Erfindungsgegenständ darum, bei einem Instrument zum Untersuchen von Körperhöhlen oder Körperröhren, sowie von technischen Gegenständen zum parallelen Versetzen der optischen Achse des Sehrohres zwischen dem Objektiv und der diesem benachbarten ersten Umkehrlinse eine schräg gestellte Planparallelplatte oder zwei entgegengesetzt gerichtete brechende Prismen anzuordnen. Auf diese Weise ist es möglich, bei gleichbleibendem Innendurchmesser des geraden Sehrohres und verringertem Durchmesser der Objektivtefe neben diesen im Rohr eine Lichtquelle in Gestalt einer elektrischen Glühlampe unterzubringen.The use of such dioptric means is in itself already multiple. known. Compared to these previously used dioptric means the subject matter of the invention is an instrument for examination of body cavities or body tubes, as well as of technical objects to the parallel Displacement of the optical axis of the periscope between the objective and the latter adjacent first erecting lens an inclined plane-parallel plate or two to arrange oppositely directed refractive prisms. That way it is possible, with the same inner diameter of the straight periscope and reduced Diameter of the objective in addition to this in the tube a light source in the form of a to accommodate electric light bulb.
In der Zeichnung ist der Erfindungsgegenstand in zwei Ausführungsformen zur DarstelIung gebracht.In the drawing, the subject of the invention is in two embodiments brought to the display.
In Abb. i ist a das Besichtigungs- bzw. Beleuchtungsrohr, in welchem zwischen dem Objektivsystem b und der ersten Umkehrlinse c eine planparallele Glasplatte e angeordnet ist, welche schräg gestellt zur optischen Achse die Parallelverschiebung derselben bewirkt. Hierbei btfindet sich vor dem Rohre a ein kleines Obj ektivsystem b, welches beispielsweise nur halb so ;groß als die mit ihm in Verbindung stehenden Umkehrlinsen ist. Hierdurch wird über dem Objektivsystemb ein Raum/ gewonnen, welcher z. B. zur Anbringung .einer Glühlampe verwendet werden kann, die das Objekt hesonders günstig beleuchtet.In Fig. I, a is the inspection or lighting tube, in which a plane-parallel glass plate e is arranged between the objective system b and the first erecting lens c, which, at an angle to the optical axis, causes the parallel displacement of the same. In front of the tube a there is a small lens system b which is, for example, only half the size of the erecting lenses connected to it. As a result, a space / is gained above the lens system, which z. B. for attaching .einer light bulb can be used, which illuminates the object particularly favorably.
Die Ausführungsform nach Abb.2 unterscheidet sich von derjenigen nach Abb. i dadurch, daß statt der Glasplatte e zwei entgegengesetzt gerichtete brechende Prismeng zu gleichem Zweck vorgesehen sind.The embodiment according to Fig.2 differs from that according to Fig. I in that instead of the glass plate e two oppositely directed refractive Prisms are provided for the same purpose.
Der Erfindungsgegenstand eignet sich nicht nur für medizinische Untersuchungen, insbesondere in Körperhöhlen. und -röhren, sondern läßt sich mit demselben Erfolge auch zum Prüfen von technischen Gegenständen, z. B. zur Besichtigung des Bodens von Bohrungen. in Werkstücken und vorzüglich zur Beobachtung der Seitenwandungen solcher Teile oder Einrichtungen bis auf den Grund verwenden.The subject matter of the invention is not only suitable for medical examinations, in particular in body cavities. and tubes, but can also be used with the same success for testing technical objects such. B. to inspect the bottom of boreholes. in workpieces and especially for observing the side walls of such parts or devices down to the bottom.
Durch die Kombination des kleinen Objektivsystexns mit den größeren. Umkehrlinsen wird ein wesentlich helleres Bild erzielt, als dies möglich wäre, wenn das ganze optische Instrument nur den gleichen -geringen Dardh.-messer des Objektivsystems hätte.By combining the small lens system with the larger ones. Erecting lenses produces a much brighter image than would be possible if the entire optical instrument only has the same -small Dardh.-meter of the objective system would have.
