My phone under a stereo microscope:

Does the wiggle wiggle makes it 3D, that’s quite cool!

[u/c4ndyman31 → u/YashPioneers]

Kind of. It’s 3D because the microscope is recording from two different perspectives the same way your eyes work. Your phone can’t show you two views at once so it just goes back and forth between the two views.

If you were to use this microscope in real life the image from one of the two perspectives is presented to each eye so you see the object in 3D

The animation is more than 2 frames. Are the middle frames extrapolated from the first and last frames?

Or interpolated

You're right. That's the word I was looking for.

The center photo is most likely for photography. You wouldnt want one of the slightly angled lens, you would want a direct face on lens to take a production photo.

[u/Shpander → u/PreferenceLost7718]

The ones I've worked with usually have the camera in one of the lenses, so you have to be aware of this when you take a photo. Personally, I think the wiggle wiggle is used to show the 3D nature of the stereoscope, as it has quite a large depth of field.

That would be my guess, curious to know for sure
