Abstract
A microscope adapted for use by two or more operators during surgical operations has a main objective lens and at least two mutually independent stereoscopic observation beam paths. Each stereoscopic observation beam path has a magnification system and a focusing system disposed therein. Pupil displacement systems are provided in modular construction of different mechanical lengths but of equal optical path lengths. This modular construction allows individual and customized configurations of the microscope for adaptation to meet the needs and requirements of various operating conditions and the various operating disciplines.
