Re: [ATM] testing flats with a green laser

Ah, the one that doesn't have the lower level spread sprectrum as
the filter vinyl works best when it has only the hsarp lines to
seperate out and pass the green one through.
I'll note that the same bulb also works well without any filter
at all although the fringes aren't quite as visible but there is
a lot more light so the fringes still show up nicely.
When I was matching a pair of mirrors for a Stecick-Paul, it was
easy to walk out to the hallway where there is a flourscent light
from the bathroom where I do my work and get the fringes  just
standang there with the glasses.  The glass does need to be dry
tho and that oftentimes was the problem as I was polishing them
out to the same ROC.
