Duncan,
Oops, just took a look at a recent IEEE AP magazine and found that the
fellow I had in mind made precision coaxial lines for measuring dielectric
constant and permeability, not refractometers (as far as I now). Here's
his contact info, just in case that's still of interest to you (who knows,
he may have experience with refractometers as well!):
Damaskos, Inc.
P.O. Box 469
Concordville, PA 19331, USA
+1 610 358 0200 (tel)
+1 610 4558 1019 (fax)

Regards,
Greg
