Abstract

A stereoscopic microscopic providing at least one pair of stereoscopic optical paths comprises an objective system, a first focusing lens having a first optical refractive power and a second focusing lens having a second optical refractive power and at least one actuator. The first optical refractive power and the second optical refractive have different signs. The objective system and the first and second focusing lenses are commonly traversed by the at least one pair of stereoscopic optical paths, respectively. The actuator shifts at least one of these first and second focusing lenses along the at least one pair of stereoscopic optical paths to change the working distance and/or to vary an optical refractive power of at least one of these first and second focusing lenses. The first focusing lens is immediately neighboring the objective system along the at least one pair of stereoscopic optical paths.
