at one time I sold Camera that were mounted to electron scanning

one I personal was involved with was the on in the botony building at
cornell university
the professors there told me that a bus driving 1/4 mile away cause so much
vibration to render the microscope useless
so the scope was mounted to a 12 foot by 12 foot 25 foot deep slab of
reinforced concrete
This is normal. Mass is your friend. I have a small slab poured here
which is isolated from the rest of the building foundation and has the
lathe and turntable mounted on it. It's only a fraction of that size
but it seems to do pretty well.
I sure there were more details about suspension and stuff but this is what
it takes to eliminate common vibrations from devices
The lower the frequency, the more mass it takes.

It's not just the mass, it's also isolating that mass from other
vibrations. There was a time when such slabs were floated in a pool of
mercury, which effectively decoupled it from the ground. However, since
the demonization of Mercury, I doubt it's still used anywhere.
