Problems solved by technology

This solution has proven to be disadvantageous in that the two objectives are in a fixed position relative to each other, so that the free space is greatly restricted by the second objective in the standby position and facing the user

Embodiment Construction

[0048] Unless otherwise indicated, the drawings are viewed collectively below. The same reference numerals denote the same components. These examples are intended to be specific examples of the invention and should not be construed as limiting. The above description related to the claims leads those skilled in the art to generalize and change the embodiments described herein.

[0049] figure 1 A microscope 1 is shown, such as is used in particular in the field of electrophysiology. A supporting element that can be raised and lowered in the focusing direction is indicated by 2 . Mounted on the support 2 is a nosepiece including an objective lens. For focusing, the support 2 can be raised and lowered. The sample stage and the sample placed thereon are fixed on the stand 34 of the column of the microscope 1 . After the sample stage is positioned, the sample stage will not move due to the contact vibration sensitivity of the sample to be tested. In research observations, th...

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

technical field [0001] The invention relates to a nosepiece, in particular for a microscope, comprising a nosepiece for at least two objectives, and also to a microscope with such a nosepiece. Background technique [0002] Such nosepieces are known from the prior art. In the known objective lens turret, a plurality of objective lenses are arranged around and fixed on the support and the desired objective lens can be turned into the working position by the rotation of the support. In addition to this objective lens turret, the objective lens converter is also known. In the objective lens changer, the objective lens can be individually moved from the parking position to a working position shared by all objective lenses. [0003] The latter nosepiece has proven to be advantageous especially for use in the field of electrophysiology, since a greater free space around the objective and the sample can thereby be provided. Typically, when used in the field of electrophysiology, t...
