ABSTRACT:
A stereomicroscope of the telescope type includes a first beam path and a second beam path, wherein in the first beam path a first telescope system and in the second beam path a second telescope system are provided, wherein the magnifications of both telescope systems are equal and can be changed synchronously to each other, and wherein a common main objective is allocated to both beam paths. In order to increase the resolution without loss in depth of field, it is proposed that at least one optical element of the first telescope system has, compared to at least one corresponding optical element of the second telescope system, a different optically effective diameter.
