I've been thinking about chemistry. Long ago I developed, not from first principles, but from old formulae, a physical developer for Holograms. The idea was that if one developed the plate with a developer that could enhance the actual interference pattern on the plate by giving it a physical structure, it could be used as a master to make metal replicas for pressing white light Holograms. It worked and we were able to make very good impressions in various kinds of plastic from nickel replicas of the Holographic plates. This was a quite different process to that used now which utilises a photo resist. The developer, to start with, had a dozen components. Slowly, but surely, I reduced them and finally ended with two solutions with only four components - they were mixed 1:1 for use. By the way, the resolution obtained was 750- 850 lines per mm.
I think the same will happen with this new black coating process. It will be further developed and simplified until it becomes a marketable product. Two solutions (perhaps) one to coat, the other to treat the surface. It will never be cheap. _______________ Dr E D F Williams http://personal.inet.fi/cool/don.williams Author's Web Site and Photo Gallery Updated: March 30, 2002 ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, February 07, 2003 1:13 AM Subject: Re: Black black paint > Thanks Robin Hood! > So it appears to be a process that would be used for metal parts in optical gear, that could reflect light, but probably not edges of lens elements. > > BR > > "Dr E D F Williams" <[EMAIL PROTECTED]> wrote: > > >I've broken the law.
