Re: Inverted Stereomicroscope-Got it!

OK, Put together the inverted stereomicroscope. An old Zeiss SM off the back shelf, a 90 degree connector from an OPMI, and a binocular from a ophthalmologists' slit lamp. All fits together mechanically, and actually works optically!

Just need to build a stage now!

Zeiss Standard

I have this little Zeiss Standard Junior. It has the condenser in place. It also has the flip in 1.5x tube lens. Mechanically good.
A good frame for a build project.
$30 plus actual postage.
Thanks!

Re: Zeiss Universal UEM Industrial

Still available, but going on eBay soon. Let me know if you're interested.
If you need a head, binocular, or stage for it, I may have it. Contact me for prices.
Thanks for looking!

Re: Zeiss DIC slider

That might work. Parfocality is not a concern. This objective will end up as part of the illuminating system. I could probably use any brand of objective- it just needs to be about 10-15x with long working distance, and RMS threads. I'll shop through eBay to try to find something suitable. The will ...

Re: Zeiss DIC slider

Thanks 75RR and PeteM,

That's helpful.
I don't want to buy the lambda plate. I'm thinking of machining a plate out of aluminum.

This is for my DIY Lightsheet illumination project. I need to put a patterned screen in the rear focal plane of the objective. I thought this might be the easiest way.

Re: Seeking selection advice for stereo microscope

I've had a Meiji stereo microscope for about 20 years. It's held up pretty well. Good for general purpose work around the lab.
Here's a link to it on Amazon:

Might be worth looking at.

Thanks 75RR, The motorized Z-axis is good for computerized scans that are going to last many hours. I wrote to ASI for a price quote. Probably out of my range.

Re: Zeiss Universal Focusing Block

75RR, Not to change the subject, but do you have the ASI motor Z-axis controller for the universal? Seems like it should also fit the Standard WL. I like ASI products, especially their light sheet microscopes. The Z-drive would be handy. We have motor drive on all our microscopes at work; it would b...

Re: 1962 ad, perhaps of interest

It looks like those medical students are taking a practical exam under the watchful eye of their professor. I would recommend moving those microscopes farther apart. It looks like the medical student on the left is staring at the answer sheet of the student's clipboard in the middle.

Re: Zeiss Universal Focusing Block

Well, I have taken an old, black, metal-knobbed focusing block and put it on a later model Universal with no problem.
I looked through all my microscopes, but they all have metal knobs now.

Should be 100% interchangeable. Go for it!

Re: "Fibres" common topic? Did you make interesting observations or photos?

Here's a tiny little slide called "Japanese Tissue". I don't remember where I got it. I think it was in a box of microfossils I purchased at the fundraiser for the Paleontological Society. Anyway, here's the photo of the fibers. I'm not sure what type of fibre they are, but I'm guessing rice fibre o...

What would be the specific advantages of an inverted stereo? OK, what if you want to examine the ventral surface of a small aquatic invertebrate, perhaps a small insect? You could flip it over, but it would flip right back. You could kill it and then flip it over. But what if you want to observe so...

Re: Zeiss Experts: What Model is This?

The Standard WL come up on eBay often enough. There was a nice one just a few weeks back. Here's a few photos of my Standard WLs. Maybe just to show that they can be configured in a multitude of ways, from simple to complicated. The black is probably as good as the gray. Either is fine.

Re: Zeiss Experts: What Model is This?

The Standard WL is a great research grade microscope. It has parts interchangeable with the other Standards, as well as the Universals.
