ABSTRACT:
A universal tube for microscopes has the shape of a block (1) whose front side bears an eyepiece attachment (2) and whose other sides are provided with image inlet or outlet openings (9-13) for auxiliary units which can be selectively attached. For the selection of the proper individual image inlets or outlets, depending on what auxiliary units are attached, two beam switching locations are provided within the tube, at which locations the beam may be deflected. The first switching location has three prisms fastened on a turret (5), each of the prisms having a reflection surface which is located in the same place in all switch positions of the turret and serves for coupling the eyepiece attachment to the different beams. The second switching location is where the optical axes of the individual image inlets and outlets (9-13) intersect each other. These inlets and outlets are provided with guides (14) along which interchangeable mirror elements can be inserted up to the point of intersection of the axes.
