Abstract
The microscope stand foot serves to accommodate an illumination device having optical components and having an aperture diaphragm and field diaphragm. The latter are assembled in a cylindrical tube held by a carrier, the tube being able to be fastened in the stand foot as a prefabricated unit. In this way, the assembly of the illumination device is simplified. When fastening the carrier in the stand foot, the tube rests under tension on mating surfaces, as a result of which an adjustment of the tube and thus of the optical components is dispensed with.
