When I wrote:
You all should know that there will be a light source coming soon (the patent has been applied for) that will enable one to enlarge on Azo. The light will not be hot, exposure times will be relatively short, and the whole thing will be reasonably priced. "
I hope I did not give the impression that I was coming up with the light source. This is someone els'e invention. No, there is no focus shift. I'm not sure what part of the spectrum is being used. It is a trade secret, at least for now--and even I don't know. Paula and I are just helping to test it.
