Yes, provided that the objective has a RMS thread.
This combination is usable, although that would not be advisable for some reasons:
1) The focal length of some producers’ tube lens (180mm) is not the same as that of other manufacturers. As a result, the magnification of the objective would not be precise.
2) Aberrations would be introduced because other companies correct for lateral chromatic aberration in the tube lens.
3) The objective probably would not be parfocal with Optika objectives.
