I WAS saying 'the Japanese import almost all of their > optical glass'. Marc is right. There is a bit of irony in this situation though. Walter Kluck, now retired General Manager of what was Leitz Canada was discussing optical glass during lunch at the '95 Lexington LHSA meeting and I asked about sources. He said that much of his premium material came from Japan. Perhaps Japan is a more efficient producer of intermediate optical glass. John Barnabas - ---
