Re: 50X objective recommendation

I'm using it with a Raynox DCR-150 with roughly 180 mm tube length. Adding another 25 mm extension to bring it closer to 200 mm doesn't change the very tight working distance. Bummer. Is image quality good at least? It looks like they made these mitutoyo/akashi hardness testers for some tiem so the...

Re: 50X objective recommendation

Your tube lens not being focused to infinity could change the working distance. How do you have it set up?

Re: Diff between Mitu M Plan Apo 5x at 100mm and Mitu QV 2.5x

On eBay they are marginally cheaper than m plan apos, depending on the day. I keep meaning to test my qv 1x vs my m plan apo 2x. Visually performance seems about the same, but I couldn't get the spacer off the qv, hence getting the normal one.

Wild 1x and 0.8x photo relay lenses--tube lens potential?

Just a quick thought that has been in the back of my head for a while. Back in the day afocal imaging was the standard camera hookup method for a few brands, including Zeiss, Leitz and some Wilds. This would use either a normal viewing eyepiece or an extra well corrected photo eyepiece to project th...

Re: Mitutoyo QV Quick Vision Machine Teardown

The TLs should be 100, 200 and 600mm, since the QV-objectives are rated for 100mm standard. Ah, of course. It's right on the objectives so I guess I'd have no reason to doubt them. That would suggest pretty insanely heavy cropping of the image circle even at nominal 1x. I appreciate the offer of th...

Re: Olympus BH-2 Camera adapter

Very nice! I'd be curious to see how well the photo eyepiece matches up.

Re: Mitutoyo QV Quick Vision Machine Teardown

Very interesting! I've often wondered what might be inside one of these. With such a small sensor I kind of wonder if any of the rumored corrections are real, or if it really does just crop any of the slightly aberrated zone of the image. We know they don't mind going into deep diffraction given the...

Re: Olympus BH-2 Camera adapter

Yeah, the photo eyepiece you have there is from a different brand. It may be partway compatible or it might not br, best to get an Olympus nfk given the quality of your setup. For the mechanical adaptation the official adapter for an SLR was the olympus Photomicro L. It is one of the nicest looking ...

Re: 50X objective recommendation

This is an obscure objective which may not have been made by mitutoyo themselves (sometimes also labelled asahi I think?) Off of a hardness tester.

Re: 50X objective recommendation

Vibration issues will only be worse at 50x if 20x is a problem. You might want to consider getting a heftier stand like a measurescope base or something like sorbothane for vibrational isolation. Having done 20x shots with a wobbly base I'd definitely recommend it as a quakity of life improvement. W...

Re: 50X objective recommendation

What do you find difficult about the 20x? The 50x mitutoyo is definitely expensive, and aside from the super long working distance and parfocality its lower reaolution isn't ideal for photography anyway. You might find an Olympus umplanfl or lmplanfl or mplanfl 50x, they are occasionally inexpensive...

Re: Introduction and quick question

Ah, a compound scope. That makes more sense. You mught find it's too fine for convenient usage.
Misremembered which brand. Amscope and parco are both just importers selling much of the same stuff. These meiji lookalikes are mostly pretty similar.

Re: Introduction and quick question

Looks like you are off to a good start. As a quick note, unless you have a specialized adapter your amscope will not fit into a bausch and lomb stand. The amscope has a modern standard 76mm round mount, while bausch and lomb has an ideosyncratic rounded rectangular mount. Adapters were made by a few...

Re: Edges of the stacked image is distorted

That's coma and/or astigmatism (both I think?). Details blur in a line towards the center (coma) and in a line perpenicular to that (astigmatism) depending which way they're out of focus, and stacking algorithms can't help interpret it as these starbursts. It's inherent to the optics, not the progra...
