Abstract
A convergence tube for stereomicroscopes in which both observation beam paths are inclined relative to one another at an angle of convergence &agr; and image inversion elements are provided in both observation beam paths. Four planar reflectors R,to R,are provided in each of the two beam paths and are arranged relative to one another in such a way that the axis beams incident on and emergent from the reflectors R,, R,lie in a common plane E,, the axis beams incident on and emergent from the reflector R,describe a plane E,that forms an angle &bgr;=90°+&agr;/4 with the plane E,, and the axis beams incident on and emergent from the reflector R,describe a plane E,that forms an angle &bgr;,=&agr;/2 with plane E,.
