EMI2.1
Auf der Zeichnung ist als Ausführungsbeispiel der Erfindung ein zweigliedriger Linsenkondensor mit zur Seite drehbarer Dunkelfeldblende dargestellt. Fig. 1 ist ein Längsschnitt, Fig. 2 ein Querschnitt nach der Linie 2-2 der Fig. 1. In einem Kondensorgehäuse a sind zwei Kondensorlinsen b1 und b2 gelagert. Vor denselben befindet sich zunächst eine die Dunkelfeld-

scheibe < P trägt, die unter der Annahme, dass dem Kondensor parallele Lichtstrahlen zugeführt werden, dieselbe Grösse besitzt wie die Dunkelfeldblende c.
Ferner ist in dem Kondensor eine Irisblende e eingebaut, deren Fassungsring e1 durch seinen Flansch e2 zusammen mit der Büchse tll mittels eines eingeschraubten Ringes al im zylindrischen Teil des Kondensorgehauses a festgehalten ist. Der bewegliche Ring z2 der Irisblende e wird mittels eines durch einen Schlitz des leam. gcringes e1 hindurchtretpiJden Ansatzes es gedreht, an den ein durch entsprechende Aussparungen am Kondensorgehäuse a und an der Büchse d1 hindurchgeführter Handgriff f mit zwei Schrauben f1 angeschraubt ist.
Dieselben Schrauben f1 befestigen an dem Ansatz e4 des beweglichen Irisblendenringes e3 ausserdem noch eine kleine Büchse g, in der sich ein durch diese BÜchse gefÜhrter und durch eine Schraubenfeder h nach oben gepresster Mitnehmerstift t mit einer kegelförmigen

EMI2.1
As an embodiment of the invention, the drawing shows a two-part lens condenser with a dark field diaphragm that can be rotated to the side. Fig. 1 is a longitudinal section, Fig. 2 is a cross section along the line 2-2 of Fig. 1. Two condenser lenses b1 and b2 are mounted in a condenser housing a. In front of them there is initially a dark field

disc <P, which, assuming that parallel light beams are fed to the condenser, has the same size as the dark field diaphragm c.
Furthermore, an iris diaphragm e is built into the condenser, the mounting ring e1 of which is held by its flange e2 together with the bushing tll by means of a screwed-in ring al in the cylindrical part of the condenser housing a. The movable ring z2 of the iris diaphragm e is by means of a slot through the leam. A handle f passed through corresponding recesses on the condenser housing a and on the bushing d1 is screwed with two screws f1.
The same screws f1 also attach a small sleeve g to the shoulder e4 of the movable iris diaphragm ring e3, in which a conical driver pin t guided through this sleeve and pressed upward by a helical spring h

Adjustment of the iris diaphragm to change.
PATENT CLAIMS: l. Microscope condenser fu! Dark-field lighting and bright-field lighting that transcends voluity, in which the dark-field lighting is generated by means of generated peripheral tufts and central shielding and which is covered by the central aperture during the dark-field lighting
EMI2.4
de. ; Brightfield image takes place by actuating a single handle.
