Re: Working in an "universal condenser" for Nikon Optiphot
Shading like that is common with slightly mismatched DIC prisms, isn't it?

Re: A microscope for Christmas….
Apart from the question of how much money spent, I think the most relevant question is what it is going to be used for. Absolutely. If there's no strong direction a stereo is a good general purpose scope that's easy to use and practical (splinter removal). But it's not good for hunting tardigrades.

Re: Working in an "universal condenser" for Nikon Optiphot
That is fascinating. As you say I don't know if it's bad news for the dic or if it's good news for the oblique. Probably the latter, you're getting really good lighting. Probably time to try it on some diatoms or other classic fun subjects.

Re: SMZ-10 OPTICAL AXIS COLLIMATOR
The problem is usually in the head, not the zoom body, even if nothing is loose. Not 100% of the time but usually. You'd need to mix and match with known good components to isolate the issue. It's never an easy fix, usually not really possible without factory tools unfortunately.

Re: Good Stereo Microscope?
Yeah, a good SZ7 is a remarkable scope, especially with the 15x uwf eyepieces. Just a bit annoying to get a good copy, though quite inexpensive.

Re: Good Stereo Microscope?
Yeah, it's a lot of scope for the money. You can also keep an eye out for Olympus SZH-10s which have similar specs, maybe not quite as good with the default df plan 1x objective but with the bonus of sometimes having a dual-objective revolver to extend the magnification range.

Re: Good Stereo Microscope?
Yes, the 508's 8:1 is going to feel very similar to the 10:1 on the smz-u. The 508 is rated apochromatic but not planar. The 0.075 numerical aperture of the 508 is lower than the ~0.1 of the smz-u ed plan 1x so it will resolve less and be less bright, though color correction may be better on the 508...

Re: Good Stereo Microscope?
Less than a used trinocular or even binocular 508 typically goes for, if you can even find one. Heck, probably less than trinocular 2000s usually go for.
Seriously, a used trinocular 508 sold for 2400 on ebay a couple weeks ago. An smz-u can be had for half that.

For someone who considers a Zeiss 508 expensive a Nikon SMZ-U is not exactly a bargain. An smz-u on the used market is typically cheaper than a 508 and probably more capable (though much less compact, the 508 is superb within its niche). Thank you for offering. I don't have the experience to judge ...

Slides are usually expensive too. I am kicking myself because I can't...

Re: Good Stereo Microscope?
Wysiwyg is difficult on a stereo because the true 3d view will always look better than the single 2d image the camera gets.
The smz-u is an excellent stereo and often a crazy value.

The mysterious Bausch and Lomb Monozoom 4
Here's an odd speck of history. Years back i was researching the Bausch and Lomb/Cambridge/Leica Monozoom 7, and in trying to find the exact year it was released (1985?) I found a much older reference to a 'Monozoom 4' in 1979 in a German laser journal. The google preview was limited but I managed t...

Re: Nikon plan 1x stereo Objective
Yeah, m60x1, just like ol' grandpappy (the M8). It's very cool that they revived that standard--I wonder if the plan 1x design is a direct descendant too.
Of course you can also directly mount a Zeiss SteReo objective on it too same thread (if they didn't cost a million skillion dollars).

I' surprised to see it listed as 3ph1. I was sure it was just m50x1. They did use 3ph1 on the z swries though.

It isn't threaded--it has a bayonet mount. If it's anywhere close to 300 it would be a total steal, though I suspect it's a bit more.

Re: Nikon plan 1x stereo Objective
The m50/60/80 do have an m60 thread but the nikons do not, they're m58x0.75. Iirc adapting one of the clone plan 1xes on a wild m8 worked but vignetted a bit. That said my adapter made it sit lower than ideal.

Re: SMZ-10 OPTICAL AXIS COLLIMATOR
Yeah, this lens can be improved on by replacing with a more recent equivalent. Really the special part of the smz-10 is the head, if that's in good shape putting it on a newer smz series body or one of the Chinese clones would be an improvement.

Re: Increase FOV
It'll be interesting to see if you can push it that far. As is if my calculations are right you are pretty close to using the full rated image circle of the better objectives but they can often be pushed a bit further.

Re: Usin Mitutoyo objective on Olympus BHMJ
Olympus bh2 eyepieces apply corrections that are needed for olympus objectives. Mitutoyo objectives need no further corrections so the nfk eyepiece will degrade the image.
