Abstract

A microscope includes: an objective turret holding a micro and a macro objective for rotation to operational positions along an optical axis; observation optics in an imaging beam path, and an illumination device including a beam splitter for generating an illumination beam path and coupling the illumination beam path into the imaging beam path, the macro objective including a first subsystem attachable to the objective turret, and a second subsystem insertable into the imaging beam path between the turret and the observation optics when the first subsystem is operational, the illumination device allowing a telecentric beam path with an illumination pupil produced by either the micro objective or the macro objective, and adjustment optics in the illumination beam path having positive refractive power and causing the illumination pupil to be shifted to a rear exit pupil, located between the first optical subsystem and the beam splitter, of the macro objective.
