Abstract:
1. A surgical microscope comprising: a stand; a pivot support connected to said stand and movable relative to said stand; an optics carrier connected to said pivot support, said optics carrier being rotatable relative to said pivot support about a horizontal pivot axis, said optics carrier including a center of gravity at a location determined by said optics carrier and any optics carried thereby; a guide carriage for connecting said optics carrier to said pivot support; and an arc-segment-shaped guidance element arranged to guide said rotation of said optics carrier relative to said pivot support, said arc-segment-shaped guidance element having a virtual central axis, wherein said pivot axis of said optics carrier coincides with said central axis of said arc-segment-shaped guidance element and said arc-segment-shaped guidance element coacts with said guide carriage to guide said rotation of said optics carrier about said pivot axis, and wherein said arc-segment-shaped guidance element is connected to said optics carrier to permit relative displacement between said arc-segment-shape guidance element and said optics carrier to allow said center of gravity to be aligned with said pivot axis.
