Abstract
The invention describes an apparatus for changing objective lenses in a microscope, the microscope being used primarily with a microscope stage that has a so-called fixed stage arrangement. The disposition of the objective lens turret in the microscope makes it possible to avoid damaging manipulators or samples during an objective lens change. The damage is avoided due to a lateral tilt of the rotational axis of the objective lens turret relative to the first and the second side walls of the microscope. The lateral tilt of the turret also ensures that a particular part of the sample remains located in the field of view of the microscope after the lens change. The entire process of objective lens change, as well as the magnification setting and focusing necessary for the purpose, is performed in a completely automatic and motorized fashion.
