Re: Advice on buying Stereo Microscope

The m1 is an ultrabasic student scope. No way to change the magnification aside from changing thr main objective. I would not bother with one, if you want a long working distance microscope a nikon smz-1 or smz-2b will cost similarly and have better functionality, or you can spend a bit more ans get...

Re: Help with model of Southern Precision Instrument Microscope

SPI is (was?) a whitebox importer, no collectible value. It looks to be missing one eyepiece and some camera hardware (which is fine because you'd need to replace it anyway). It is probably a solid starter scope if it powers on and thr insides aren't moldy or hazy.

Re: Buying 3rd Party Eyepieces for stereo scope

Most stereos have at most minor correctiona done in the eyepieces, so that part of compatibility is less important. You'd want to be sure your scope takes standard 30mm stereo eyepieces--any recent mid to high end one will (unless you get one following Meiji's in hoise 30.5mm standard) but these low...

Re: PZO DIC on a BHT microscope, possible?

In adapting a Nikon labiphit head to a BH2 Olympus body the Nikon head actually needed to sit higher than the bottom of the olympus dovetail to keep the focus position in the eyepieces about the same, so the extra space of a mechanical adapter was actually helpful.

Re: Taking pictures with a stereo scope

If you want to focus stack just be aware the image will move horizontally as you focus in, that's just as it should be. These basic ones with one or two fixed mags are cheap and basic, but you may be surprised by what a good image it produces. I tried a similar one a while back at a sales office and...

Re: what is a 1x objective ?

Remember that '1x' is just relative to the field number, and in a microscope the image will always be further magnified (either by the eyepieces or from the small camera sensor to a large monitor.) A few sellers might label a flat shield as a '1x' auxiliary objective (since it does not change the ma...

Re: Using a pair of cameras with a stereo microscope

If dual viewing for video is the goal there are double photo attachments available for some stereo microscopes, including the Nikon SMZ line and the Wild/Leica m series (the latter being surgical beamsplitters). That would probably be the most convenient method for video, though not the cheapest.

Re: Very bad image quality when using polarizers on a microscope, why?

I don't think they put much effort into mitigating that issue beyond putting a quarter wave plate above the analyzer to depolarize the light before it interacts with any flat surfaces. It might be worth trying with an appropriately oriented circular polarizer for your analyzer. I don't think this is...

Re: "Pol" objectives in macrophotography under non-polarized, incident light

If Jena corrections are similar to Zeiss west objectives missing the eyepiece is likely to cause some noticeable trouble, though if you only capture the very center of the field of view it may matter less.

Low strain glass only matters to polarized light, so unpolarized light doesn't really care either way. It should be fine in that respect.

Re: Swift Achromat vs Nikon Fluor

To me the improvement in color correction looks pretty dramatic, and definitely makes for much nicer photos. I suppose that suggests the swift system is neither non-correcting or at least weakly correcting, at least on CA.

If you're asking 'can we identify which microscope was used to take a photo' the answer is no.

But that's guesswork, since there isn...

Re: 7X-45X Dual Lit 6W LED Trinocular Stereo

This is a typical problem. These cameras have extremely tiny sensors, and even with a 0.5x reduction lens you get an enormous crop factor. If you don't have a 0.5x adapter it will improve things dramatically, to the point that it's usable (though perhaps annoying).
