    • 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 R1 to R4 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 R1, R2 lie in a common plane E1,2, the axis beams incident on and emergent from the reflector R3 describe a plane E3 that forms an angle &bgr;=90°+&agr;/4 with the plane E1,2, and the axis beams incident on and emergent from the reflector R4 describe a plane E4 that forms an angle &bgr;2=&agr;/2 with plane E3.
    • 用于立体显微镜的会聚管,其中两个观察光束路径以会聚α相对于彼此倾斜,并且在两个观察光束路径中提供图像反转元件。 四个平面反射器R1至R4设置在两个光束路径中的每一个中,并且相对于彼此布置成使得入射到反射器R1和R2的轴光束位于公共平面E1,2中, 入射在反射器R3上并从反射器R3射出的轴光束描述与平面E1,2形成角度β= 90°+α/ 4的平面E3,并且入射到反射器R4并从反射器R4射出的轴线束描述平面E4, 与平面E3形成角度β2=α/ 2。
