Abstract

An illuminating device for a stereo microscope having an objective with variable imaging focal intercept includes first coupling mechanism, which effects a coupling between the imaging focal intercept of the objective and the likewise adjustable focal intercept of the illuminating optical system, separate from the observation optics, in such a manner that the illuminating focal intercept is in agreement with the imaging focal intercept of the objective. Moreover, adjusting mechanism is provided for the defined adjustment of the diameter of the illuminated field. In particular, the illuminating device is suitable for a surgical microscope.
