Just glancing at the Schott website Schott Duryea Glass 
<http://www.us.schott.com/optics_devices/english/products/flash/abbediagramm_flash.html> 
and noticed a
page set I had not seen before: Borofloat 33.  The ecode is 473654; it
has about half the expansion rate of N-BK7.  Comes up to 1 inch thick.

Wonder if it has high enough quality to be used as L-H correctors and
be cost effective.
