Abstract

A pancratic magnification system for at least two observation beam paths within a stereo microscope consists of a first and a second optical component that are displaceable in a defined manner along a common optical axis, following which a third, stationary, optical component is arranged. Variation of magnification is achieved by means of defined displacement of the first two optical components. A focusing on a desired object plane can be effected by displacement of only the first optical component. The pancratic magnification system is arranged after a common main objective for said at least two observation beam paths within the stereo microscope.
