  Optisches Gerät zum Untersuchen von   Eörperhöhlen   und   Körperröhren.   



   Die Lichtfilter optischer Geräte zum Untersuchen von   Körperhöhle   und   KörpI'lTöhren   (z. B. von Kystoskopen und Gastroskopen) hat man bisher auf mancherlei Art ausgebildet. So hat man z. B. planparallele gefärbte Glasplatten als Filter verwendet oder gefärbte Gelatinesehiehten, die auf Glas 
 EMI1.1 
 färbte. 



   Nach der Erfindung lässt man als Filter Kittschichten verkitteter Glieder des optischen Systems dienen. Diese Art der Filterung hat den Vorzug, dass dazu kein besonderes optisches Element erforderlieh ist, da die in Frage kommenden optischen Geräte, wenn sie nicht allzu unvollkommen sein sollen, z. B. stets mit   verkitteten   Linsen ausgestattet sind, so dass nur an Stelle des bisher verwendeten farblosen Kitts ein entsprechend gefärbter Kitt verwendet zu werden braucht. Dabei sind diese Filter von dem Nachteil frei, der den gefärbten Linsen anhaftet, dass nämlich die Filterschicht an verschiedenen Stellen verschiedene Dicke aufweist. 



   In der Zeichnung ist als Ausführungsbeispiel ein der Erfindung entsprechend   gebautes   Innenrohr 
 EMI1.2 
   Kanadabalsam   miteinander verkittet sind.

  Optical device for examining body cavities and tubes.



   The light filters of optical devices for examining body cavities and body tubes (e.g. of kystoscopes and gastroscopes) have hitherto been designed in various ways. So one has z. B. plane-parallel colored glass plates used as filters or colored gelatinesehte that on glass
 EMI1.1
 colored.



   According to the invention, cement layers of cemented members of the optical system are used as filters. This type of filtering has the advantage that no special optical element is required, since the optical devices in question, if they should not be too imperfect, e.g. B. are always equipped with cemented lenses, so that a correspondingly colored putty only needs to be used in place of the previously used colorless putty. These filters are free from the disadvantage that adheres to the colored lenses, namely that the filter layer has different thicknesses at different points.



   In the drawing, an inner tube constructed according to the invention is an exemplary embodiment
