ABSTRACT:
The invention is directed to an illuminating arrangement (5) for a surgical microscope (1) having an illuminating beam path (7) which runs essentially coaxially to the optical axis (9) of the surgical microscope. The illuminating arrangement (5) includes an optical ancillary element (15) having a positive refractive power. The ancillary element (15) can be selectively pivoted into and out of the illuminating beam path. The illuminating aperture in the region of the optical axis (9) of the surgical microscope (1) is increased by pivoting the optical ancillary element (15) into the illuminating beam path (7). This is done without changing the viewing focal intercept of the surgical microscope (1).
