Abstract
For focusing an operation microscope within a defined focusing range, a main objective and parts of an illuminating device are arranged in a focusing module that is separate from the microscope body. The focusing module is movable along the optical axis in a defined manner by means of manual or motor drives, so that focusing on a desired object detail is possible. Desired fine focusing can thus take place, in addition to coarse focusing by spatial positioning of the operation microscope by means of a stand. The advantages are a compact design, prevention of reflections through the main objective, and widely varied possibilities for filling of additional accessories.
