Re: replacing Nikon FX-35A camera

It is straightforward. Loosen the top set screw on the tan tube, under the viewfinder eyepiece. Lift the camera assembly out. Thr bottom of thr camera assembly has an OD of 42mm. It is possible to remove the camera from the top, hollow out the middle bit which has an obsolete shutter mechanism and b...

Re: FAQ: Screw Threads we use

To be more specific it's a Nikon universal rotating nosepiece with epi DIC prisms for a finite optiphot. A bit confusing since it feels unlikely that it would be a matter of them being loosey goosey with their own spec--this would have likely been one of the first implementations of it, I think. May...

Re: FAQ: Screw Threads we use

Not to muddy the waters, but I just got a Nikon finite m26 threaded bd nosepiece and my mitutoyos thread onto it smoothly and without issue.

Re: microscope infinity optical system setup for wild bees macro photography?

I have a hefty measuring stand, and even on my wood floor and not insanely solid table it does not have noticeable vibration problems at 50x. Maybe I have lucked out in its placement though. Do you have an idea of your budget range? That will have a big effect on suggestions--that mitutoyo 50x for i...

I cannot be certain, but many Nikon objectives correct CA and the flat field through the use of their (proprietary) tube lens and eye pieces.
They do not. Nikon has been fully internally corrected since the biophot in the mid 70s.

Wonderful shots! I am an especial fan of the crab. The lighting is exceptional.

Re: High NA 2.5x pushed to 5x VS 5x

This is pretty cool--what sensor size are you using? The qv isn't really a 2.5x in microscope specs though so it's sort of cheating. I think I've read thst normal QVs don't quite measure up to the m plan apos, but the HR variant seems like a real winner. I only have a normal '1x' and I like it, but ...

Re: Wanted Please - Amscope MU  Series digital microscope eyepiece camera 

No idea. It doesn't ship with toupview, it came with some other software (I hope I can find that CD again).
It would be cheap to try anyway, but not sure what chances of success would be.

Re: Wanted Please - Amscope MU  Series digital microscope eyepiece camera 

I have a similar Hayear unit, nominally 5mp. Probably the same oem. I didn't like it much and would be happy to part with it.

Re: Darkfield Adapter for Whole Slide Imaging

This looks extremely rad.
There are fiber optic light guides that end in a flat bar rather than a rpund point. I wonder if these would be flat enough to use on a setup like this.

Re: Meopta lens problems

They could be grimy. There could be internal mold or delamination. You'd need to have a close look at them. A stereo microscope works well for this type of inspection.

That's too bad, though not necessarily a dealbreaker depending on the subject. How short are we talking, roughly?

Re: advice for Nikon Labophot trinocular head

I just got a 3D printer so I figured I'd have a try at designing something to hold my surplus shed 125mm doublet in position. https://i.imgur.com/oie26c4.png Holder for the lens (with cover) which press fit into an m42 spacer. https://i.imgur.com/XBsLGal.png Threaded into position.

Re: Stack Comparison with pics: Lomo 4 vs Lomo 3,7 vs Zeiss 3,2

This is a very interesting set!
I notice the lighting is different with the lomo 4x vs the other two (fewer highlights). Is it because of lower working distance?
