I wonder if they have to "tare" the prisms before use. Can they machine or cut, that close for those time frames?

Now maybe we can get close to DFTing an electron. Just a few more magnitudes quicker in time. If we could put a hard x-ray through it. One clean emission from a single electron. Or maybe placing six detectors around an electron while reflecting an X-ray laser.
