Dr. Olsson,

Corning has agreed to make this very thin PYREX wafer for you again.  (4"
Diameter x 170 microns thick). You should have already been contacted by
customer service.

Large wafers that are very thin are difficult to machine, handle and ship.  We
originally "no-quoted" this inquiry without looking into our records to find
that we have successfully made this before.  Our apologies for this confusion.

Regards, Dan

thin wafers to us anymore.
