Abstract: A multi-axial objective, comprising a number of adjacently arranged elementary systems which are formed by three spheres, the centers of which are situated on the same line, said systems being symmetrically arranged with respect to the center of the central sphere. The refractive index of the central sphere is larger than the refractive index of the outer spheres. The entrance and the exit of each system are adjoined by windows which form an entrance pupil and an exit pupil, the former being arranged in the center of the entrance sphere, while the latter is arranged in the center of the exit sphere. The windows are proportioned with respect to the diameter of the spheres so that the field of each system overlaps the field of the directly adjoining systems, the field image of the multi-axial objective being uniformly illuminated.
