Please Identify this Nikon S Series.

[GWD]

Hello, I just acquired this vintage Nikon Microscope, I'm having difficulty nailing down the model. Any help you can provide would be appreciated.

Welcome to the forum.

Thanks for the welcome, I've read the article, it's not mentioned or pictured.

[zzffnn]

Does it help you in any way by knowing the exact model number? It is probably a combination of catalog numbers representing different major parts. For example, S-Kt with F head and R stage.

Most, if not all, parts between different models of S series are interchangeable. Some parts from model G can even be used in model S. Previous owner may have moved/changed parts around.

[GWD]

I understand the different components such as the type 'U" trinocular head and the type "R" mechanical stage. The part that has me stumped is the base; the Koehler Illumination assembly slides forward and backward on a dovetail, the two adjustment screws on either side of the dovetail adjust the alignment of a mirror located in the base, and there is a wheel on the right/rear side of the base that controls an iris. Also, the focus assembly is different, it's not coaxial like the ones in the aforementioned article, the course and fine adjustments are separate.

I've looked online and have seen one or two other Nikons with this base configuration but there is no indication as to their model. My guess is that it may be an early model S-Kt but I'm not sure.

I've also contacted Nikon MicroscopyU, and the person I'm in contact with there is also stumped.

Going back to the article, the author refers to a type "T" base, used for "Differential Interference Microscopes", I suppose it could be one of those, but there isn't enough information to make a determination.

My Nikon G uses two separate focus knobs like that. Such a swap is also possible, by previous owner.

[GWD]

I know it isn't a swap, this booklet was included with the purchase, it shows the exact same configuration, also indicating a model "S".

Thanks! But it isn't in that catalog either. The back of the booklet has a code (64.4.A) I, maybe it's a mid 60's model?

Nice setup.

Not sure whether you've already solved it out by yourself, but a helping hand anyway.

Your setup is definitely a S-Ke. The Ke base intended for the S stand has 2 major generations (if including the Ke stand from the L-Ke, it would be 3.) Your Ke base is the 2nd version of the 1st generation (the 1st version has the older Nippon Kogaku prism mark rather than the Nikon sticker) The change from the Gen1. to Gen2 happened somewhere around 1965-66. So, your model make is from around 1962-1965 I guess.

Cheers!

"Microscope Mike" is an academic who loves his nikon scopes.
He also hangs out of photomacrography.net (as mtuell I think).
(I think he was talking about s-series just recently....)

Thanks,GWD, for a thread which thoughtful form microscopists offered their experiences..and their links to assist you with.

I'm going with zzffnn (hi,Fan) suggestion that your stand was cobled by parts from a variety of Nikon S stands.

To see when your stands most recent component was incorporated into this stand you now care for...what is the serial number on your stands trinoc head? On my trinoc head (same trinoc head as yours..., my stand has: Nikon 68092, made in Japan.

My trinoc S-series came with a DIC large cylinder attachment for it's vertical port...visually looking through this large cylinder...the color of light was red. I traded this component for the S-series field lens, a field lens I do not use.

I tricked my stand (Nikon S-series) with: Plan 10, Plan 20, Flour 40, a semi-plan 60...(err...thank you Fan for this terrific 60X objective), and Plan 100 objectives...all Nikon, except the 60X objective. Nikon 1.30 NA substage condenser, and Nikon 6V/30Watt square filament tungsten bulb fron a Nikon inverted stands field illuminator.


Thanks all, charlie guevara with a tricked out Nikon S series trinoc stand I have no use for! charlie guevara
Please let us all know the serial number of your stands trin-noc head..it starts the process of when your stand was: 'cobbeled from parts'. Your thread has had comments with terrific links to aid my understanding of my Nikon stands...thank you all for this thread! charlie guevara

Nice LUR-Ke set, Charles! (Hi!)

From my personal collection. Nikon S (Bi-axial focusing early version) manual circa 1963.
The manual provides the Ke illuminator base (Gen1. version1) as an add-on accessory.

The model G,GH doesn't come out until 1966, and though the focusing is very similar,
the fine focusing block is greatly simplified. (The strut protruding downwards from the
model S fine focusing block houses a balancing spring, and the model G,GH fine focusing
block is redesigned, negating the need for the spring.)

P.S. don't try to dissassemble the model S fine focus module. there are 3 springs inside that
are balanced on counteracting levers holding up the stage. Dislocating the parts means painful
reassembly, 3 strong springs in a impossibly small space...

Hi, Did you manage to identify your Nikon scope? I've just bought the similar model!....can't find any info apart from a few snaps!
I see the binocular head has a slightly different design to the rest of the 'S' range!
