Description

Beleuchtungseinrichtung für Mikroskope Die vorliegende Erfindung betrifft eine verbesserte Beleuchtungsanordnung für - solche Mikroskop-Auflichtkondensoren, bei denen das Beleuchtungsstrahlenbündel das abbildende System nicht berührt und mittels Ringspiegels dem Objekt zugeführt wird. Sie bezweckt eine günstige Strahlenführung imBeleuchtungsbündel und eine bequeme Regelung derApertur. Ferner liegt hier die Möglichkeit vor, durch geeignete Blenden dem Ouerschnitt des Beleuchtungsbündels an geeigneter Stelle eine bestimmte Form zu geben, was dann wichtig ist, wenn gewisse Azimuteffekte durch einseitige Beleuchtung hervorgerufen werden sollen. Nebenbei hat man noch den Vorteil, daß innere Reflexe im Beleuchtungssystemstark vermindert werden. Für die Regelung der Größe des beleuchteten Feldes kann eine veränderliche Blende an geeigneter Stelle vorgesehen werden.Illumination device for microscopes The present invention relates to an improved lighting arrangement for - such microscope incident light condensers, in which the illuminating beam does not touch the imaging system and is fed to the object by means of a ring mirror. It aims at a favorable radiation guidance in the lighting bundle and convenient control of the aperture. Furthermore, here is the Possibility in front of the cross-section of the lighting bundle by means of suitable screens to give a certain form at a suitable point, which is important when certain Azimuth effects are to be caused by one-sided lighting. Alongside there is still the advantage that internal reflections in the lighting system are greatly reduced will. To regulate the size of the illuminated field can be a variable Aperture should be provided at a suitable location.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Bei a liegt das von einer nicht gezeichneten Lichtquelle mittels einer Linse erzeugte Bild dieser Lichtquelle. Am gleichen Ort oder in dessen Nähe ist die zweckmäßig als Zentralblende ausgeführte Blende b angeordnet, die als Aperturblende wirkt und gemeinsam mit dem Lichtquellenbild mittels der Linsen c und d und des Spiegels e am Auflichtkondensor f abgebildet wird. Durch die Blende b ist demnach Apertur, Form und Richtung des Beleuchtungsbündels bestimmt. Das Objekt ist mit g bezeichnet; das Objektiv, von dem nur die Linsen dargestellt sind, mit h. Die nicht benutzten Teile der Linsen c und d können zur Verminderung von Linsenreflexen abgeschliffen und mattiert sein.An exemplary embodiment of the invention is shown in the drawing. At a is that generated by a light source (not shown) by means of a lens Image of this light source. In the same place or in its vicinity it is useful arranged as a central diaphragm diaphragm b, which acts as an aperture diaphragm and together with the light source image by means of lenses c and d and mirror e is imaged on the incident light condenser f. The aperture b is therefore the aperture, Determines the shape and direction of the light beam. The object is denoted by g; the objective, of which only the lenses are shown, with h. The ones not used Parts of lenses c and d can be ground to reduce lens flare and be matted.
