I have an interest in Macro and Micro photography, see my Close Up web page. A tripod is awkward to use and a stand to hold the camera is much more user friendly. This is much more than just a camera stand, it's a complete system including a lower illumination light source and there are many accessories that I don't have including some fantastic (read Expensive) lenses.
This is a 1970 to 1980 time frame macro photography setup by Nikon. See their Multiphot Museum web page.
This system was designed to span the gap between 1:1 images that can be taken using just a camera and close up lens and the above 10x power were a microscope works best.
So the range of magnifications is on the order of 1X to 10X. It can also be used with a trinocular microscope for higher powers.
Here's their suggested magnification range using the Micro-Nikkor lenses made for this system. Showing only 35mm data.
Lens
Magnification
120mm f/6.3 M39 Leica (Wiki)
1/3 to 4x
65mm f/4.5 M39 Lieca
3.5 to 10x
35mm f/4.5 RMS (Wiki)
8x to 20x
19mm f/2.8 RMS
15x to 40x
I don't yet have any documentation on this system so will not name the parts now. If you have any sales brochures, manuals, etc.
The lamp housing is missing that fits on the horizontal rail leading to the Diascopic illuminator. I need one of them.
please let me know if you can help.

Some of these have a binocular head as standard and so in stock form can not be used for photography, but there's a optional trinocular head that will accept one of the camera adapters (FMF, PFM, HFM, EFM CFM). The trinocular head comes standard on other models.
These are also referred to as the V-series microscopes.
Notice that with the exception of the Multiphot, all the other microscopes mount the camera so that it's weight does not tend to move something.
When you mount a camera on a classical microscope it will tend to push the tube down so only very light weight cameras can be used.
This is one of the reasons the August Köhler patented a microscope where only the objective moves and the eyepiece and stage fixed. This system makes use of the tube lens and has what's called infinity optics.
The phot microscopes have the eyepiece fixed to the stand and move the stage for focus.
All of the "phots" are based on a 160mm tube length and 45mm parafocal distance. The objectives will be marked 160/- (no cover glass) or 160/0.17 (0.17mm cover glass).
Some of these are the older type that require matched objectives and eyepieces to make some optical corrections.
The newer ones use CF (Chrome Free) objectives and CF eyepieces where there's not eyepiece corrections.
The newer series of microscopes are the Eclipse models that use the CFI60 (CF Infinity optics with 60mm parafocal distance instead of the prior 45mm parafocal distance).
These objectives have 25mm threads instead of the RMS threads used on the prior models.
The Eclipse microscopes call the head the "eyepiece tube" because that's where the tube lens is located. There are both binocular and trinocular tubes available for the Eclipse models.
Also there are a number of accessories that fit below the eyepiece tube such as a 1" tall spacer to raise the eye level of the oculars.
1967
Apophot
Part of the "S" series (black) Nikon microscopes.
Uses 160mm tube length objective with 36mm parafocal length. Not the more modern chrome free (CF) objectives.
Along with that is the need to match the eyepieces to the objectives to get all the corrections.
1970 - 1980
Multiphot
This is really more a camera than a microscope although it can be
used with a camera.
1976
Biophot

No provision for a camera and not really a phot.
This is the introductory/teaching inverted microscope.
Note the linear interplanetary distance adjustment.
Uses the 6V 20 Wall halogen lamp.
Note 3-hole phase slider on the light source.
1987
Optiphot -77 & -88 Wafer Inspection & Pol
Semiconductor inspection microscope designed for epitaxial illumination (from the top through the objective lens)
Optiphot Labophot Diaphot Micropho all use same filter cube
The wafer inspection scopes can use Nomarski, DIC or BD objectives and so have 26mm threads.
-66 for 6" diameter wafers Note: Some Optiphot versions do not have an optical system in the base.
-88 for 8" diameter wafers Note: Some Optiphot versions do not have an optical system in the base.
-Biological Does have both top and bottom (50W ext lamphouse) illumination.
- Pol a Polarized light version "Pol" which uses a 50 Watt external lamp house to make up for the loss of light through the polarizing filters.
-100S
This one (maybe the biological version?) seems to have the option of getting light
for either or both the top and bottom
(two lamp houses)
Also shown is the older film camera adapter that
allows using the fine focus telescope which is not
needed with digital cameras with Live View (Wiki).
Live View plus the ability to magnify allows for
great focusing without the complication of the old system.
Uses the type-F trinocular head (notice no push/pull on side).
This one has a large X-Y movement range yet has light from below?
Without light from below (Diascopic illumination)
Only the top lamp house, the wafer inspection/metallurgical version
that uses 210mm TL BD objectives with 26mm threads
Bottom only Illumination (POL or Biological) 50 W Lamp
Probably RMS 160mm type objectives with 45mm PF dist.
-100S Top only illumintion. More modern than other Optiphot designs.
Using CF EPI infinity objectives. Note modern design vertical illuminator
and what's probably an infinity trinocular head.
A stereo microscope allows seeing in 3D which is great for working where your hands are doing something, like Surface Mount Technology. The microscope becomes part of your feedback system between the eye, brain and hands allowing much finer work that you can do with just eyesight alone.
A binocular microscope also has two eyepieces, but only one objective lens so while you look through both eyes you do not have stereo 3D vision. I mention this because recently I've seen some microscopes on eBay with stereo in the title, but they were compound microscopes with binocular heads.
Note that the image is erect, that to say when you move your tweezers to the right the image goes to the right. This makes movements intuitive.
It turns out that looking at things like pond water is awkward with a compound microscope, like the Labophot, because you really don't need high power. So I've started looking into a stereo microscope with more than 30X. That power comes from my existing B&L StereoZoom 4
There are two types of stereo optical systems.
Microscope U -Fundamentals of StereomicroscopyIn the patent for the CMO scope, AO said one of the problems with the greenough design is that the eyepieces are rotated when changing the interpupillary distance and that can cause discomfort in the viewer.
Greenough design
You can see that in the Greenough design
the two optical paths are not parallel,
but instead come together at a point.
Because of the tilted optical path
there may be more distortion
of the object being viewed.
Although the depth of field in the eyepieces is good
it's not good when photographed.
Common Main Objective
The light path is parallel and makes use of a
common main objective lens (12 in patent dwg).

2901943 Stereoscopic microscope, American Optical Corp, Sep 5, 1956
B&L StereoZoom 4
This microscope has a variable zoom of 0.7 to 3.0 power for the objective which with a 10X eyepice gives 7x - 30x.
It is of the basic Greenough design. It uses high quality mirrors to get an erect image and to tip the eyepieces angle for comfortable viewing.
Nikon SMZ-U
I'm considering getting one of these if the price is right. It's of the CMO design and has a 0.7 to 7 zoom range which with a 10x eyepiece gives 7x to 70x, a much wider range of powers than the B&L SZ4. It also has more modern optics as well as supporting a separate tube for a camera, or with an optional side port two cameras.
