[0012]This object is solved according to the invention by an objective changer according to claim 1 and a corresponding mic

Problems solved by technology

Such manipulations require a large free space around the object.
As the entire swinging area of the objectives has to be kept free of manipulators, this objective changer proved to be disadvantageous for some applications.
Given this solution it proves to b

Embodiment Construction

[0014]Here, it is useful when for each objective one drivable slide each is provided on which an objective holder can be mounted.

[0015]The objectives can be moved directly at their respective objective holders either manually or by a motor. Usefully, slides are provided which carry the objective holders and which in turn can each be driven manually or by a motor. For reasons of simplicity, the latter case is to be assumed in the following, i.e. the presence of a slide on which an objective holder is arranged which in turn can carry an objective.

[0016]With an objective changer of this type, thus each objective is moved substantially perpendicular to the optical axis by means of a drivable slide assigned thereto. Thus, this is not the usual arrangement of objectives on a rotating disk, where the desired objective is brought into the operating position by rotation of the rotating disk. In the typical case of application of a microscope, which is to be assumed in the following in a non-...

Abstract

An objective changer for a microscope is described, comprising a changing device for transferring at least a first objective held in a first objective holder from a first stand-by position along a first transfer path into an operating position where the first objective defines an optical axis and a second objective held in a second objective holder from a second stand-by position along a second transfer path into an operating position where the second objective defines an optical axis. The first and second transfer paths differ from each other but both extend substantially perpendicular to the optical axis at least within a first area of the first transfer path and a first area of the second transfer path.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priorities of the German patent application DE 102009026978.9 having a filing date of Jun. 16, 2009 and of the German patent application DE 102009029146.6 having a filing date of Sep. 2, 2009. The entire content of these 2 prior German patent applications is herewith incorporated by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to an objective changer, in particular for a microscope, having a changing device for at least two objectives as well as to a microscope having such an objective changer.[0003]Objective changers of this type are known from the prior art. In addition to the known objective turrets, in which several objectives are mounted on a carrier in circular arrangement and the desired objective can be swiveled into the operating position by rotating the carrier, objective changers are known in which objectives can be individually brought from a stand-by position into an oper...
