I was wondering about that at times my self!
The reason I mention this is that a couple a months ago, I went to get new
glasses, and they were touting what they called 'invisibles'- which were
PLASTIC lenses with an anti reflection coating!!! Obviously, this coating is
one that is put on with out heat, as the lenses are plastic, BUT- the
coating does cut down reflections considerabley, and though I have to be
careful cleaning them- as they tell you the coating is soft- it appears to
be put on after the lenses are made. I bet there is someone out there who
has access to the technology who might venture to try it on a camera lens.
IF it is a chemical process with out use of heat, then I am sure there might
be a way to cheaply apply the material to a mounted lens. Not multicoating,
certainly, but it might be the ticket on a favorite older lens! If it is an
easy and inexpensive process, then prbloems with 'cleaning' marks on
thecoating would be moot- simply recoat!
Anyone out there in the spectacle industry?
