Optical Coating Labs (NASDAQ:OCLI) is still a major player in
optical coatings -- I don't see any reference to photo equipment
in their current annual report, but they do license their patents
to other companies as well as doing manufacturing. The growth of
computers and communications has added a lot to their markets --
they make GlareGuard brand glare screens, OEM monitor faceplates,
anti-reflective flat panels for LCD displays, fiber optics, etc.
They're also one of the companies in the partnership that makes
the shifting-color ink used on the new U.S. banknote series.
I doubt any photographic company can put as much research into
optical coatings as a $200 million/year optical coatings
specialist.
