Would you suggest to stick with Nikon lenses for the above mentioned
microscopes or any good RMS threaded lens would be fine?
A 100X from Nikon is probably way too expensive for my pockets.

A modern 100X from Nikon is longer, doesn't use the same diameter
thread and is infinity corrected so it just wouldn't work. There is
nothing made world wide that uses 160mm correction. That standard is
long gone (sigh).

Thus it has to be not simply RMS-threaded but also 160mm corrected? Only
Nikon made that kind of lenses?

At one point, before 1990, every one used the 160mm standard with the
objectives having the RMS (Royal Microscopial Society) thread.


Thus, a RMS objective made before 1990, whatever the producer, is 160mm
corrected. That seems to make it easier to find a 100x used lens for my SC.
