Description

Stabförmiges Taschenmikroskop Man hat bereits die üblichen kleinen Taschenglühlampen zu solchen Vorrichtungen für die Objektbeleuchtung bei mikroskopischen Arbeiten benutzt, bei denen Präparate im durchfallenden Lichte untersucht werden. Diese Vorrichtungen versagen aber bei der Beobachtung in auffallendem Lichte, für die man sich nur schwierig eine einfache Beleuchtungsvorrichtung herstellen kann, weil namentlich im Falle stärkerer Vergrößerungen die Objektebene sehr nahe an das Mikroskopobjektiv heranrückt und der Lichtstrahl nur schwer in diesen schmalen Zwischenrauen geleitet werden kann.Rod-shaped pocket microscope You already have the usual small ones Pocket light bulbs to such devices for object illumination at microscopic Works used in which specimens are examined in transmitted light. However, these devices fail when observing in striking light, for which is difficult to make a simple lighting device, because, especially in the case of higher magnifications, the object plane is very close to the The microscope objective moves closer and the light beam is difficult to penetrate into these narrow roughness can be directed.

Die vorliegende Erfindung löst dieses Problem, eine helle und kleine Beleuchtungsvorrichtung für die Beobachtung in auffallendem Lichte zu verwenden, welche in den Abbildungen der Zeichnung in einer Ausführungsform gezeigt ist. Die Vorrichtung hat einen solchen Reflektor, wie er neuerdings für Taschenmikroskope in Füllfederhalterform in den Handel gebracht wird, welcher in einem Kreissegment um das Mikroobjektiv herumgeführt ist und außerdem zum Aufstützen des Instrumentes dient. Das kleine Lämpchen ist am Reflektor zwischen der inneren Fläche und dem Objektiv so angebracht, daß es von außen mittels eines durch einen Schlitz greifenden kleinen Griffes in der Höhe nach Bedarf verstellt werden kann. Die Batterie befindet sich entweder am Mikroskoptubus oder auch entfernt von dem Instrument, etwa in der Rocktasche des Benutzers, und ist durch eine Zuleitungsschnur mit der Lampe verbunden. Die Vorrichtung ist in verschiedener Weise ausführbar, doch hat sich die beschriebene Anordnung besonders bewährt. Sehr zweckmäßig sind die kleinen Zwerglampen, bei denen hinter der Glashülle ein weißer Reflektor vorgesehen ist.The present invention solves this problem, a bright and small one To use lighting equipment for observation in conspicuous light, which is shown in the figures of the drawing in one embodiment. the The device has such a reflector as it has recently been used for pocket microscopes in the form of a fountain pen on the market, which is in a segment of a circle is guided around the micro objective and also to support the instrument serves. The little lamp is on the reflector between the inner surface and the Lens attached so that it reaches from the outside by means of a through a slot small handle can be adjusted in height as required. The battery is located either on the microscope tube or away from the instrument, for example in the The user's skirt pocket and is connected to the lamp by a supply cord. The device can be implemented in various ways, but the one described has proven itself Arrangement particularly proven. The small dwarf lamps are very useful a white reflector is provided behind the glass envelope.

Nach den Abbildungen ist eine Schraubverbindung zwischen der Lampe und der Leitungsschnur zur Stromquelle vorgesehen, doch läßt sich die Verbindung auch in einer anderen wirkungsgleichen Weise ausführen.According to the pictures there is a screw connection between the lamp and the cord to the power source provided, but the connection also perform in a different manner with the same effect.

Die Anwendung der erwähnten Mikroskope mit der erlindungsgemäßen Beleuchtungsvorrichtung ist in allen solchen Fällen angebracht, wo bei nicht zu starken Vergrößerungen Metalle, Schriftfälschungen, Kleidungsstücke auf Blutspuren u. dgl. untersucht werden sollen, also beispielsweise in der Kriminalistik; doch lassen sich naturgemäß auch andere Aufgaben lösen, bei denen die Objekte bei mäßiger Vergrößerung im auffallenden Lichte zu untersuchen sind.The use of the mentioned microscopes with the lighting device according to the invention is appropriate in all cases where, if the enlargement is not too great, metals, Forgery, items of clothing are to be examined for traces of blood and the like, for example in criminology; but naturally others can also be Solve tasks in which the objects are exposed to light at moderate magnification are to be investigated.

Claims (1)

PATENTANSPRUCH: Stabförmiges Taschenmikroskop, bei dem das dem Objekt zugekehrte Ende offen und so weit schräg weggeschnitten ist, daß am Ende nur ein geringer Teil stehenbleibt, der als Reflektor dient, dadurch gekennzeichnet, daß am als Stütze dienenden Reflektor eine kleine Glühbirne angebracht ist, die sich z. B. in einer Schlitzführung parallel zur optischen Achse verschieben läßt.PATENT CLAIM: Rod-shaped pocket microscope in which the object facing end is open and cut away at an angle so far that at the end only one small part remains, which serves as a reflector, characterized in that a small lightbulb is attached to the reflector that serves as a support z. B. can move in a slot guide parallel to the optical axis.
