I have for sale Nikon TU Plan ELWD WD 11mm N.A. 0.60 (Thread 25mm)
The lens I sell is new, it was simply removed from the new microscope.
It's a really good lens for extreme macro , due to the large NA 0.60 and WD11
I also have a BD version (brightfield and darkfield) with a 32mm thread - the same optical system! I use it for my macro photography;-) Best results !

info about this objective:

my price is 900eur.

Hello Pawel!

I wish I had the money for an objective like this!

I have a question about the marking - I have some objectives with "OFN number" written on them - do you know what that stands for or means? I have had trouble trying to find out online.

Best Regards

The term "field of view· can be misleading, OFN refers to the diameter of the objective image circle (in this case designed for eyepieces with 25mm FN although the actual image circle often is bigger)

I'm curious about "_, A, B, C" letter after magnification meaning, is that objective revisions, may be factory code, no idea.
