Ok, here is a strange request.
I realized (with great joy) that I have 3 sets of amamorphic prisms. I removed them years ago from a very high tech worm drive (they were about $5000 new each!) They were broken of coarse.
My problem is that they have an AR coating for 650-660nm. I know this because these drives wrote to DVD RAM type discs.
I would LOVE to use them for my 445s. However the 445 simply refect off the prisms and a tiny amount goes through. So I need to "rub off" the AR coating.
Can this be done without damage to the prisms?
