Abstract
A stereo-microscope is disclosed. It comprises a common objective lens system, a first and second imaging lens systems having optical paths parallel to that of the objective lens system producing intermediate images of an object, a first and second optical path deflecting devices arranged behind the respective imaging lens systems for deflecting the respective ejection bundle of rays outwardly relative to the optical path of the objective lens system, and a first and second ocular systems arranged behind the respective optical path deflecting devices for observing the respective intermediate images. It is characterized in that a stereo angle .omega. which is to be decided depending on the base length between the first and second imaging lens systems and an observation angle .theta. which is defined between the observation optical paths of the first and second ocular systems are arranged to be equal. Another stereo-microscope is also disclosed. It comprises an objective optical system, a first and second ocular systems, a first and second erecting optical systems and devices for varying an observation angle .theta. defined between the observation axes of the first and second ocular …
