Re: "TL3000 Ergo" stand + Leica Wild M10
You won't need to cut anything, these tracks are generally held on by three bolts.

Re: "TL3000 Ergo" stand + Leica Wild M10
This could be an interesting challenge. Late wild or early wild-leica started using those proprietary track stands. It isn't easy to find them, but you would probably need a longer track than is on the boom stand mount you currently have. You can take that whole coarse/fine focus mount off but the t...

Re: Infinity objective to tube lens distance question.
To answer my own question about what distance is optimal: It's not zero. This varies between objectives and tube lenses based on real-world testing. Some infinity objectives (particularly lower mag ones) can actually perform better with a tube lens not focused at infinity. Sometimes things are opti...

Re: Infinity objective to tube lens distance question.
It matters somewhat. Increasing distance shrinks the image circle and can cause vignetting which puts some limits on how many accessories you can add. Depending on the tube lens there can be some relatively minor effect on image quality.

Re: IDENTIFY SLIDE FILTER NIKON?
I think I have seen this or a similar one sold as a Zeiss accessory before. I suspect it would clip onto the lip at the bottom of a greenough stereo microscope--you would not use this shape on the front of a CMO objective.

They are good objectives so I'd say it's worth experimenting with.

Re: Which scopes were these Nikon BD DIC objectives (infinite) used in? What turrets may they work with?
These were used on Nikon infinity optiphots and inverted epiphots, and are still offered for OEM applications. They have m27 threads, they don't make m27 threaded nosepieces for the Eclipse as far as I know but they still offer some accessories for the infinity optiphot line. These nosepieces use th...

Re: Leitz NPL Fluotar L 25/0.35 160/0.6-1.6
That's a real headscratcher. The only finite objectives I can think of with threads in that size range are for epi darkfield. Somebody must have had something very particular in mind. Or maybe it was just a general adapter for putting epi brightfield objectives onto a darkfield nosepiece and someone...

Re: Considering making an inf. frankenscope, would like epi options, have some objectives, thoughts?
If you aren't using a whole head an Olympus original tube lens is not really necessary. You will get good results from any number of well corrected third party lenses with an appropriate focal length (around 180), possibly superior results to the normal non-widefield Olympus tube lens. Something lik...

Re: Leica M80 Plan Objective
A little fringe is still visible in the images taken with the Planapo, I guess because the optics of the M80 are not apochromatically corrected (as those of the research grade stereos M125, M165 and M205). You get some fringe even with the nominally appchromatic bodies, just the nature of the beast.

Re: BX system and field number (FN) for different configurations
The regular trinocular tube projects only 22 mm to the eyepieces It projects a larger image than that even to the eyepieces. The trinocular port can cover aps-c no problem as my test showed, the quality is just a bit lower in the corners than the ultra widefield tube lens. You could probably use a ...

Re: Leica Gia
It would not be a good fit. Its sample jolding and ergonomics are meant specifically for gem usage. You can repurpose it to a limited extent but it would not be ideal and you'd be paying a lot extra for features you won't use.

Re: how scared should I be of mercury lamps
Monochrome emitters are plenty strong for brightfield fluorescence, even too strong in the blue range. Even with green (lime) which is the least efficient and thus weakest for a small emitter there was no issue on the scope I set up.

In this case there is a legitimate reason for the mount. The SZ7 has like double the reolution of other SZ family members and a fairly different optical system--its max NA of 0.2 handily beats Leica's current offerings in the series (and was equal to the recently discontinued S Apo).

Oh, the normal plan 10x is a really good objective for its price, excellent corner to corner performance even direct on full frame and it also works surprisingly well with DIC, though I'd need to retest the best slider/condenser prism combo.
