Description

Vorrichtung zum Beleuchten eines mikroskopischen Objektes. Das vor dem Objektiv eines Mikroskops befindliche Objekt vom Durchmesser a-b (Fig. z) erzeugt ein umgekehrtes und vergrößertes Bild A B, das durch das als Lupe wirkende Okular betrachtet als A1 BI wiederum vergrößert erscheint.Device for illuminating a microscopic object. The object located in front of the objective of a microscope from diameter ab (FIG. Z) produces an inverted and enlarged image AB, which, viewed through the eyepiece acting as a magnifying glass, appears enlarged as A1 BI.

Wird das Bild A B von einem leuchtenden Ringe L mit dem äußeren Durchmesser C-D und dem inneren Durchmesser A-B umgeben, so erzeugt dieser in der Ebene des Objektes a b das ringförmige und umgekehrte verkleinerte Bild d b a c. If the image AB is surrounded by a luminous ring L with the outer diameter CD and the inner diameter AB, this generates the ring-shaped and inverted reduced image dba c in the plane of the object ab.

Sollen die Strahlen des Ringes L aber das Feld a b belichten, so müssen sie so abgelenkt werden, daß die Punkte C und D statt in c und d in b und a abgebildet werden. Dies wird erreicht durch einen vor den Leuchtring gebrachten Ring einer Konkavlinse R (Fig. 2). Die Bilder der Ringelemente gruppieren und verdidhten sich dann zu einer geschlossenen Scheibe, die die Fläche a b des Objektes Überdeckt.However, if the rays of the ring L are to expose the field, they must be deflected so that the points C and D are mapped into b and a instead of c and d. This is achieved by a ring of a concave lens R placed in front of the luminous ring (FIG. 2). The images of the ring elements are grouped and then merged into a closed disk that covers the surface from the object.

Derartige Mikroskopbeleuchtungsringe, bestehend aus einem leuchtenden Ringe und vorgesetztem Zerstreuungsringe, finden, abgesehen vom Mikroskopieren, mit Vorteil Verwendung zum Beleuchten von Fadenkreuzen und Teilungen an Meßinstrumenten für Arbeiten unter Tage und für Sternbeobachtungen.Such microscope lighting rings, consisting of a luminous one Rings and scattering rings placed in front of them, apart from looking at them under the microscope, advantageously used for illuminating crosshairs and divisions on measuring instruments for work underground and for star gazing.
