I was under the impression that 3M's main business is *manufacturing*
plastics, not designing new ones. (Actually, I was under the impression
that 3M manufactures finished products that have plastic _in_ them, but
I guess they probably sell raw plastic to other people...)

Really? I thought *all* transparent materials have an IOR different than
air. As in, it's impossible to *avoid* this (e.g., if you wanted to make
a kind of "invisible glass", you can't do it.)

I thought that all of those claims were radically exaggerated marketing,
and that these materials are basically identical to what we had 40 years
ago.
