Does the NA not drop at lower mag settings? I know it does on some systems (macroscopes like the az100 or the leica z series), presumably since the objective is only really high res at the center where it counts at higher zoom settings, and stopping down at lower mags makes the ce ter match the lowe...

The Olympus szx7 is in their current top line of research stereos, though at the bottom of the top. It has some modularity and high quality apochromatic optics. In theory you could get a trinocular head for it, though this being a newer line means I don't rember seeing any for sale loose and it woul...

Here's a cheap motic k500 that just came up. ... "Interesting" that is being listed under the well-respected name of Mitutoyo ... is theirs a re-branded Motic, or is this a typo ? MichaelG. It could either be they put a motic scope on a mitutoyo base (the base does have mitutoyo written on it) or m...

Here's a cheap motic k500 that just came up. I just can't justify picking it up but someone should.

There are a few places on the other side of the country from California, but if you're anywhere near Raleigh NC I have a few scopes here I could show you. Consider this another vote for used, by the way. You can get something excellent for under your budget. I started on a cheap chinese Amscope ster...

I'll probably just use a bit of tape to make the eyepiece sit a bit higher to force it to be parfocal. That will put it outside its designed range but we'll see if it wrecks the image too badly. Updates to come when the canon adapter arrives.

A canon EOS xs is pretty cheap and has the bare minimum needed for a microscope camera. Adapting it without cropping might be a pain since a 1.6x or 2x projective eyepiece costs a fortune but there is the option with a 10x and a 50mm lens at infinity (afocal? I haven't tried it myself).

0.5x shouldn't crop much on a .5" sensor. I have a .6x for my 2/3 sensor and the image is about what you see through the eyepieces. Microscope cameras definitely have different priorities. Streaming data off quickly is a big one, though I am not sure to what extent a smaller sensor helps with that. ...

I will--I got a large collection of somewhat dirty eyepieces a while back, both b&l and ao, so I probably have something that will work after cleaning anyway. I have to wait on the adapter to get a good test in, but from my crude tests holding the camera above an eyepiece in (a 147b, a 146 out of on...

I forgot to ask over on PM, but what diameter is the hole at the top? 42mm or 38mm? If it is 42mm I think there is a nikon adapter that goes from 42mm to 38mm. From there you can get a diagnostic instruments 38mm adapter, 1x for a 1" sensor, .5x for a .5" sensor, etc. Anyway, I think that would work...

Thanks, I'll have to track down another appropriate AO eyepiece if I don't already have one somewhere. That does look the same as the topcon adapter, and a bit cheaper than the one I bought. I'll keep that in mind for next time, since I have another one of these topcon adapters. By the way, if anyon...

Excellent, just like an sz7. I guess I will get that adapter and then try out some eyepieces to find the right power.

I hope it's OK to revive this thread. I picked this beauty up with at my last local university surplus sale. https://i.imgur.com/vY7vDE4.jpg This baby is pretty tricked out, with both a trinoc port and the switchable 1x/2x objective. The head's prisms were loose, perhaps the reason it was released t...

I will buy this off your hands. I will use it on my M7S. Looks like it is compatible with it.

I'm sorry, it actually sold earlier today (pending a question). If that falls through I'll send you a PM.

If you don't mind the look this is a very cheap and effective solution: http://www.microbehunter.com/microscopy-forum/viewtopic.php?f=12&t=7329 You'd want to get an nfk 2.5x eventually for full frame, but the 3.3 you already have would probably be just fine for the mean time it would just produce so...

Yeah, you wouldn't see crystal structure in any case, quartz just fractures like glass. Some crystals (like salt or feldspar) show cleavage planes when they break which can tell you about the crystal form but quartz isn't so obliging.

Because there is no sign of the crystal structure in these images the suggestion is that at microscopic level one could hypothesise that if archaic pottery is analysed to ask questions about human cognition and agency one could expect similar structural characteristics however I would suggest that ...

This one has been brewing for a while. A few weeks back I got my hands on a Wild M3 (the original model)--it's an OK scope, very well built but with the distinctive pincushion distortion that they fixed in the M3b and onward. The head as an attached focus rack which accepts a 20mm shaft. That's not ...

Yeah, their price is crazy, but I do have it lower here than it will be on eBay.

I honestly don't know enough about coaxial illumination to have a sense of what problems are possible. It will definitely be mechanically compatible with the M8, and the mag range isn't that different between it and the m3 so that at least shouldn't be an issue.. This page does list it as m8 compati...

Absolutely. Here are a few more, I can take specific ones on request.

There's another clone I have seen on the market every now and then... https://i.imgur.com/I4B2k8t.jpg Even at used prices which get down to 350 occasionally (and I saw one for 150 which was gone fast), with a fixed 20x mag it sure feels like you might as well use a binocular loupe or buy a cheaper s...

SOLD 1 Wild M3 Coaxial illuminator. Asking $50 plus shipping. https://i.imgur.com/knW4n27.jpg I recently got my hands on an old Wild M3 (it was supposed to be an M3z, but oh well). I'm currently working on a stand for it which will be its own little thread, but it came with a coaxial illuminator whi...

Not to piggyback too blatantly onto the topic, but I have been wondering what about the lens itself separates two given objectives of similar working distance and magnification but different resolution. Is it using the appropriate exotic glasses, precise placement of the lenses, physical shape of th...

What is the world coming to where someone might be a bit protective of their expensive optics....

SOLD Hi everyone. A while back I went to an estate sale for a man who had been a microscope enthusiast. Most of the microscope stuff had been put together into a couple big rubbermaids, so I had to buy it all to get what I was after (as well as a few things I didn't know I was after!) Included in th...

I hope you enjoy them! Please post your impressions when you get them in.

I have an Olympus SZH (a very nice stereo scope), with a trinocular port. I found adapting a DSLR a bit difficult, as the 38mm external diameter dovetail isn't very standard. I did find a Diagnostic Instruments L clamp which fits on the dovetail, but this accessory is designed to pair with their own...

A few thoughts. I wouldn't necessarily count on a new Leica lasting 30 years. Maybe they have improved but many of their scopes have a reputation for having durability problems (likely due to how much plastic is in them). Certainly I have heard it about the MZ6. Either way you won't want to be stuck...

I've poked at the motic site some. The k400 is definitely an m5 clone. The k500 is specced and has an external look like an M3, so I'd guess that it is mz-compatible. The m700 looks like an m7a or similar. Just make sure 5ou get the k400 accessory.
