Abstract
Description
Die Erfindung betrifft einen piezomotorischen Z-Trieb für Mikroskope, insbesondere für einen, einen Objektivrevolver tragenden, am Mikroskopstativ verschiebbar gelagerten Schlitten zur schnellen und hoch präzisen Positionierung von im Objektivrevolver eingesetzten Objektiven.The Invention relates to a piezomotor Z-drive for microscopes, in particular for a person carrying a nosepiece, on the microscope stand slidably mounted carriage for fast and high-precision positioning of lenses used in the nosepiece Objective.
Eine häufige Anwendung in der Mikroskopie ist eine schnelle Stapelaufnahme von einer Probe oder einem Objekt, bei welcher in einer schnellen zeitlichen Folge Aufnahmen in verschiedenen z-Ebenen gemacht werden, wobei die z-Richtung die Richtung der optischen Achse des Mikroskopstrahlenganges ist. Aus diesen Aufnahmen kann dann z. B. ein 3D-Modell des zu untersuchenden Objektes oder der Probe berechnet und dargestellt werden. Eine solche Stapelaufnahme, bei der durch eine Verschiebung des Objektivs oder, bei feststehendem Objektiv, durch Verschiebung des Objekttisches die Fokusklage in der Probe bis auf wenige 1o Nanometer genau eingestellt werden muss, kann grundsätzlich von einem normalen, durch einen Schrittmotor angetriebenen Z-Trieb des Mikroskops durchgeführt werden, wobei allerdings die Verstellgeschwindigkeit sehr gering ist. Des Weiteren können die Schrittweite und auch ihre Reproduzierbarkeit nicht mit der erforderlichen Genauigkeit realisiert werden.A Frequent application in microscopy is fast Pile shot of a sample or object in which a fast temporal sequence recordings in different z-planes be made, with the z-direction the direction of the optical Axis of the microscope beam path is. From these shots can then z. B. a 3D model of the object to be examined or the sample calculated and presented. Such a pile recording, at by a shift of the lens or, with a fixed Objectively, by shifting the stage the focus suit in the sample has to be adjusted exactly down to a few 10 nanometers, can be basically from a normal, through a stepper motor driven Z-drive of the microscope are performed, wherein However, the adjustment speed is very low. Furthermore can the step size and also their reproducibility can not be realized with the required accuracy.
Um eine schnellere und präzisere Verstellung eines Objektivs während einer Stapelaufnahme zu erreichen, werden derzeit zusätzlich zum motorischen Z-Trieb piezo-getriebene Aktoren eingesetzt, welche jedoch auch erhebliche Nachteile aufweisen.Around a faster and more precise adjustment of a lens to achieve during a batch capture, are currently in addition to the motor Z-drive piezo-actuated actuators used, which, however, also have significant disadvantages.

So liegt der Erfindung die Aufgabe zu Grunde, einen piezoelektrischen Z-Trieb für Mikroskope zu schaffen, mit welchem eine schnelle und hochpräzise, reproduzierbare Verstellung und Positionierung eines in Richtung der optischen Achse des Mikroskopstrahlenganges (Z-Richtung) verstellbaren Tisches oder Revolverträgers ohne zusätzliche Z-Triebe über einen großen Verstellbereich realisiert werden kann.So the invention is based on the object, a piezoelectric Z-shoot for creating microscopes with which a fast and high-precision, reproducible adjustment and positioning of a in the direction of the optical axis of the microscope beam path (Z-direction) adjustable table or turret carrier without additional Z-drives realized over a large adjustment range can be.
Erfindungsgemäß wird diese Aufgabe durch einen piezoelektrischen Z-Trieb für Mikroskope gelöst, welcher mit den im Hauptanspruch dargelegten Mitteln realisiert ist. In einem weiteren Anspruch sind Einzelheiten der Erfindung offenbart.According to the invention this task by a piezoelectric Z-drive for Microscopes solved, which with the means set out in the main claim is realized. In another claim, details of Invention disclosed.
Um eine hochpräzise Verstellung der betreffenden Mikroskopteile oder Baugruppen, beispielsweise eines Mikroskoptisches oder eines Revolverträgers, sowohl zur Realisierung einer Grob- als auch einer Feinverstellung zu erreichen, ist es günstig, wenn ein erster Teil der Beine des mindestens einen Piezomotors derart angesteuert ist, dass dieser erste Teil fest mit dem Mikroskoptisch und/oder mit dem Revolverträger des Mikroskops in Wirkverbindung steht und dass ein zweiter Teil der Beine des mindestens einen Piezomotors in eine dem Vorschub entsprechende Richtung und um einen dem jeweiligen Vorschub entsprechenden Betrag gegenüber dem ersten Teil der Beine verstellt ist.In order to achieve a high-precision adjustment of the relevant microscope parts or assemblies, for example a microscope stage or a turret carrier, both for the realization of a coarse and a fine adjustment, it is advantageous if a first part of the legs of the at least one Piezo motor is controlled such that this first part is firmly in operative connection with the microscope stage and / or with the turret carrier of the microscope and that a second part of the legs of the at least one piezoelectric motor in a direction corresponding to the feed and by an amount corresponding to the respective feed the first part of the legs is displaced.
