We do have much of the details on these glasses in the REMIS database of
properties, as well as composition information from the released
material folders in the TIC vault.

These were just 2 of many filter glasses that Corning sold until the
1990's. The business was sold to Kopp Glass of Pittsburgh, PA. I have a
Kopp Filter Glass catalog that shows these filters have been produced by
Kopp. They have their own catalog numbers for them (CS-Number 7-56 =
" j- A& V+ ?& q4 a1 o) J6 ZCode 2540 & CS-Number 2-59 = Code 2404) , but they also maintain the
