Older Steindorff Berlin microscope models had a phase contrast condenser consisting of a standard brightfield condenser with a swing-out set of annular stops mounted below it (see here: [[ LINK ]]). It is not certain that this objective will match that condenser, because the annular stop there is marked 45x, while the objective offered here is 40x.
Only the Steindorff Berlin turret condenser (see here: [[ LINK ]]) has a 40x annular stop, and this objective is compatible with it.
I am not aware of Steindorff Berlin "Ph" objectives working with phase contrast condensers from other manufacturers. Please note: "not aware" does not mean they do not fit - but it is safer to assume they do not. In other words, you should assume that this objective will form a working set only with a Steindorff Berlin phase contrast condenser.
