Abstract
The invention is directed to a zoom system for at least two stereoscopic viewing beam paths and includes a multi-element pancratic magnification system as well as an afocal inverting system arranged downstream of the pancratic magnification system at the viewing/documentation end. The inverting system images the stereoscopic pupillary plane or the apparatus pupils of the viewing/documentation unit approximately in the center of the pancratic magnification system. The zoom system is especially suitable for a stereomicroscope.
