    Newton was a real a**hole for inventing these things. Now we all gotta deal with the stupid things.

    Just be glad we don't have to deal with Einstein Rings. Then we would have real problems.

    I found that giving the film a quick rinse after using Photoflo eliminated my Newton Ring problems. It may not be the only problem, but excess Photoflo sure seems to contribute.

    Old thread. Just order up some real 3mm antiNewton glass from Focal Point and be done with it.

    Drew, on several occations I've considered getting some Focal Point A-N glass for some of my carrier experiments/projects but never got around to it. What specifically is different/special about Focal Point's A-N glass compared to other A-N glass?

    There just aren't many choice left for true AN glass. Focal Point will custom cut your glass and edge it with
    either 2mm or 3mm stock, and they're reasonable. Etched picture frame glass isn't the same thing - it breaks
    way easier and sometimes causes minor optical issues the way it diffuses the light. At one time I had samples of
    AN glass from all over the world. The best came from Belgium. It's a fussier topic in an enlarging carrier than a
    contact frame.
