Casimir effect plates?

[coppercone2]

So I was wondering about the whole lapping laboratory/workshop thing I had in mind for quite a while and I am wondering what the flatness requirement of plates would be to get the cashmir effect to work. 

I read the separation between plates is under 10 nanometers, which is
0.000000393701 inches

For comparison, a AA surface plate is 0.0001 inches per meter or 0.0000055 per 2'' (seems like what you would imagine bench top experiment to be, looking how the pictures are presented)

So if I did the math right, the AA surface plate is only 14 times less accurate then necessary for giant 2 inch cashmir plates?

I know this is probobly really inaccurate but its surprisingly hard to find information on what this would look like, because of cookware websites.

Assuming you got something to AA grade surface plate level, how is it further flatened? I assume that the plates they made were made through some forms of self leveling molecular deposition or something.. no one actually managed to flatten something that far conventionally, have they? can you slowly peel off atoms using some kind of laser, zapper machine, etc? I was imagining a scanning ion beam that they can slowly grow things with high resolution by molecular bombardment... but I suppose maybe guidance is a problem (you get an uneven surface within the 'bombardment zone')

I say '14 times does not seem like alot' because I have no idea if lapping has some kind of catastrophic limit where it does not function anymore that makes "14 times" = infinity. Usually peoples interests go no further then gauge blocks, but this effect obviously shows the need for a flatter structure.

Are you talking about the Casimir Effect?
Never heard of "kasmir plates".

yeah, I see its written a few different ways. I mean the plates that are associated with zero point energy

I imagined two plates inside of ball positioners with peizo actuators to vary the distance, it seems that piezo stacks with 1nm adjustment are possible (16 bit 100VDC power supply is a requirement). Maybe it would require a few piezo stacks for the polar axis alignment with thick
'living hinge mechanisms', if manually adjusted ball is not good enough, to get it to 'curl' the plate in the correct direction with a few force vectors. I would built it press fit with a very thin paper coating that can be removed when its assembled so the piezos/micrometers can do their work to correctly align the mechanism to be parallel when its 'fixed' with a say 0.001 inch paper in place, so all the mechanisms would be focused on bringing an approx 0.001 inch gap to 10 nm.
