Description
Binotubus für Mikroskope Die Erfindung betrifft einen Binotobus für Mikroskope, in dem ein Strahlenteiler die abbildenden Strahlen in zwei Teilstrahlengänge aufspaltet.Binotube for microscopes The invention relates to a Binotobus for Microscopes in which a beam splitter divides the imaging beams into two partial beam paths splits.
Es sind Binotuben bekannt, in denen ein Strahlenteiler die abbildenden Strahlen in zwei Teilstrahlengänge aufspaltet und in einer der beiden Okularbildebenen eine Strichplatte angeordnet ist. Gelegentlich wird der Wunsch geäußert, in beiden Okularbildebenen Strichplatten einzusetzen. Bei einer solchen Anordnung müßten diese sehr genau übereinstimmen. Außerdem wäre es sehr schwer, beide genau auf denselben Punkt einzustellen.There are binotubes known, in which a beam splitter is the imaging Beams split into two partial beam paths and in one of the two ocular image planes a reticle is arranged. Occasionally a wish is expressed in both Use graticules in the eyepiece image planes. With such an arrangement this would have to match very closely. Also, it would be very difficult to have both exactly on the same thing Point.
Diese Schwierigkeiten werden erfindungsgemäß dadurch vermieden, daß eine Strichplatte außerhalb des das Objekt abbildenden Strahlenganges vorgesehen ist und daß das die Strichmarken abbildende Strahlenbündel vor oder an dem Strahlenteiler in den Objektstrahlengang eingespiegelt wird.These difficulties are avoided according to the invention in that a reticle is provided outside the beam path imaging the object and that the beam forming the line marks is in front of or on the beam splitter is reflected in the object beam path.
Darüber hinaus bietet die Erfindung die Möglichkeit, Strichplatten mit hellen Marken auf dunklem Grunde einzuspiegeln, was beim Einbau von Strichplatten in die Okularebenen nicht möglich ist.In addition, the invention offers the possibility of reticules with light marks to reflect on a dark background, which is the case with the installation of graticules is not possible in the eyepiece planes.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Der Binotubus besteht aus dem Strahlenteilerprisma 1 mit der, Teilerfläche 2 und den Prismen 3 und 4. In der Brennebene der achromatischen Linse 5 ist eine Strichplatte 6 angeordnet, davor ein Kondensor 7 und eine Lichtquelle B. Die vom Objekt kommenden Strahlen werden an der, Teilerfläche 2 aufgespalten. Das durchtretende Strahlenbündel wird über das Prisma 3 in die Okularbildebene 9, das reflektierte über das Prisma 4 in die Okularbildebene 10 geworfen. Dort entstehen die Teilbilder des Objekts. In diesen Objektstrahlengang wird über die unbenutzt liegende Fläche des Strahlenteilers 1 der »Strichmarken«-Strahlengang eingespiegelt. Die an der Teilerfäche 2 aufgespaltenen Strahlen liefern wie beim Objektstrahlengang Teilbilder in den Okularebenen, jetzt aber von der rückseitig beleuchteten Strichmarke 6. Beide Bilder sind so gleichzeitig sichtbar.The drawing shows an exemplary embodiment of the subject matter of the invention shown. The binotube consists of the beam splitter prism 1 with the splitter surface 2 and the prisms 3 and 4. In the focal plane of the achromatic lens 5 is a Arranged reticle 6, in front of it a condenser 7 and a light source B. The dated Beams coming from the object are split up at the splitter surface 2. The penetrating The bundle of rays is reflected through the prism 3 in the eyepiece image plane 9 Thrown over the prism 4 into the eyepiece image plane 10. This is where the partial images are created of the object. In this object beam path is over the unused area of the beam splitter 1 is reflected in the "line marks" beam path. The one at the Splitting surface 2 split beams provide partial images as with the object beam path in the eyepiece planes, but now from the back-lit line mark 6. Both Images are visible at the same time.
