Very interessting Francisco, so many forms unlike what I see around here.

What objective did you use?

Thanks dtsh
Used Objective Nikon 20X

Some saltwater diatoms

I mention that as a curiousity because very high N.A. DF condensers are uncommon and by the era that Nikon made that objective, high N.A.well corrected objectives such as that one often had an iris, so they could be used for DF with a fairly convential oil cardioid condenser as a lower magnificatio...

That probably is quite a sweet piece of glass. N.A. 1.0 appears to be only obtainable with immersion. I see multiple .95 objectives but all 1.0 I have seen are oil. Did Nikon have a DF condenser that was high enough to use that with? Thanks for the info. I don't know if Nikon had such a condenser

That's a nice one from the original CF series. Nikon never updated it (CFN) before going infinity.

Not for sale, is it?

Thanks for the info.
No, it is not for sale at the moment.

An unusual objective:
Nikon PlanApo 40X 1.0 Oil- 160mm

Different types of illumination using the Nikon Fluophot microscope

The condenser has a special anchor. It is not valid for other Nikon models.

The Brachionus rotifer hunts a Lepocinclis. Despite its efforts, the mastax cannot catch it, so it finally expels it.

Thanks apochronaut for the interesting information.

£800 in 1969? that is equivalent to £11000 today.

...according to:

Always fun, rarely useful!

Thank you.
Curious data

Some time ago I got a Nikon Apophot microscope. After cleaning and adjustment, the microscope is ready for use. The Apopphot is a magnificent, but little known, microscope. Really nice looking instrument. I have a 32 page brochure for it, that shows a 'system chart' if you have things still not ide...

Francisco, beautiful microscope, thanks for showing it to us! I'm with Pete, I've never seen one before so that makes your post doubly interesting.

Thank you.
It is a "little" known microscope

I have a Tiyoda 40x apo on my old Nippon Kogaku stand and while I thought it would require a lighter compensation as with Olympus it seems to work very well with the Nikon HK eyepieces and is parfocal with the Nikon short barrel lenses. I paid $20 for mine, so might also be something to look out fo...

Wonderful appearing scope - and the first Apophot I've seen. Thanks for posting it. It looks as if there is room to move the stage down and use 45mm parfocal objectives as well? Do the nosepiece and magnification changer use the same circular dovetails as later Nikon nosepieces? If so, it might be ...

That looks like a very nice beast of an instrument! What is the large, black, circular part on the lower right of your last image? Magnification changer maybe? What condenser is it? Looks like an achromat aplanat (nice!), but does this microscope come with any special illumination techniques? It is...
