Hello all,
been a long time. I have a question for all the lab geeks.
I want to make up some specs for a class that I'm teaching, and I WANT the factory PAL markings to stay on. I'm concerned that with even normal use and cleaning, that the marks will rub off in short order. I was thinking of having them dip coated BEFORE the markings are removed. That way cleaning the lenses will not remove the markings.
The only downside I see to that is that some of the ink may leech off into the vat and contminate the entire batch, but otherwise, should work. Don't want a spin coat on the front surface, probably going to run and streak on the convex side.
Any thoughts?
