Description

Beleuchtungsvorrichtung für Mikroskope Die Erfindung betrifft eine Beleuchtungsvorrichtung für Mikroskope, bei denen mit Fluoreszenzbeleuchtung gearbeitet wird. Es ist bekannt, zu diesem Zweck eine Fluoreszenzleuchte (Ultraviolettstrahler) in Abstand unter dem Mikroskoptisch anzuordnen und das Licht durch einen Spiegel von unten gegen das Objekt zu richten.Illumination device for microscopes The invention relates to a Lighting device for microscopes that work with fluorescent lighting will. It is known to use a fluorescent lamp (ultraviolet radiator) for this purpose. to be arranged at a distance under the microscope stage and the light through a mirror aimed at the object from below.

Da sich aber herausgestellt hat, daß es vorteilhaft ist, wenn die Ultraviolett-Strahlung von einer das Auge des Beobachters nicht direkt treffenden Quelle ausgeht, wird gemäß der Erfindung die Lichtquelle für ultraviolette Strahlung unter dem Objekttisch nahe dem Objekt, jedoch außerhalb des direkt zum Okular gelangenden Strahlenganges angeordnet.But since it has been found that it is advantageous if the Ultraviolet radiation from something not directly striking the observer's eye Source goes out, according to the invention, the light source for ultraviolet radiation under the specimen stage near the specimen, but outside of the one that goes directly to the eyepiece Arranged beam path.

Entweder kann die Leuchte seitlich von dem Rundausschnitt des Objekttisches am Objekttisch angebracht sein, oder sie kann in einem Dunkelfeldkondensor liegen, der in an sich bekannter Weise nahe unter dem Objekttisch sitzt.Either the lamp can be removed from the round section of the object table be attached to the stage, or it can be in a dark field condenser, which sits close under the stage in a known manner.

Die Zeichnung zeigt diese beiden Ausführungsformen der Erfindung. In beiden F i g. 1 und 2 bedeuten 1 den Fuß, 2 das Gestell, 3 das Okular und 4 das Objektiv des Mikroskops. Der Objekttisch 5 hat einen Ausschnitt 6.The drawing shows these two embodiments of the invention. In both figures. 1 and 2 mean 1 the base, 2 the frame, 3 the eyepiece and 4 the Lens of the microscope. The object table 5 has a cutout 6.

Nach F i g. 1 ist unmittelbar neben dem Ausschnitt 6 dicht unter dem Objekttisch die Ultra-@riolettleuchte 7 derart angebracht, daß zwar das Objekt seitlich angestrahlt und dadurch zum Fluoreszieren angeregt wird, aber kein Ultraviolettlicht unmittelbar in das Objektiv 4 gelangt.According to FIG. 1 is immediately next to the cutout 6 just below the The ultra-violet lamp 7 attached to the object table in such a way that the object is from the side is illuminated and thereby stimulated to fluoresce, but no ultraviolet light enters the lens 4 directly.

Nach F i g. 2 liegt eine Ultraviolettleuclb'le 9 in einem Dunkelfeldkondensator 8, der wie üblich unterhalb des Objekttisches sitzt. Auch dadurch wird bewirkt, daß ultraviolettes Licht das Objekt zum Fluoreszieren anregt, aber nicht selbst direkt ins Objektiv fällt.According to FIG. 2 lies an ultraviolet fluorescent bulb 9 in a dark field capacitor 8, which sits below the stage as usual. This also has the effect of that ultraviolet light makes the object fluoresce, but not itself falls directly into the lens.
