Patent attributes
A telescope-type stereomicroscope which is outfitted with an objective and two magnification changers arranged downstream of the objective. In this telescope-type stereomicroscope, the light from an object that is being examined enters the objective. Two light bundles of the light re-exiting from the objective, which are oriented parallel to one another, enter the magnification changers. The optical axes of the magnification changers are arranged at a fixed distance from one another. Each magnification changer has an entrance pupil for the light bundle associated with it. The entrance pupil has a diameter DEP that depends on the respective selected magnification, where the condition DEP>B/1.06 is met at the maximum selected magnification. Optionally, the stereomicroscope meets the condition tan(ω)≧0.16 with respect to the angle ω at which the light coming from an extra-axial point P at the object enters the magnification changers at the lowest possible magnification setting.
