What I've learned of some modern white-light interfereometry tech absolutely broke my mind until I actually understood it. Like "does not follow the laws of physics/imaging as I was taught them" but it's amazing stuff.
Barely even cutting edge anymore. I think there's a Keyence system that's pretty affordable (for a research lab) that can do z-axis into the nanometers, on a countertop, in the air in a normal lab space. No SEMs, vacuum chambers or levitating/magic/unobtanium tables necessary. I'm sure Zeiss and their peers have something similar.
