Telling if a polarizer is multi-coated?

    It would seem to me that if a polarizer is properly multi-coated, you
    should have a hard time seeing any reflections in the surface. Is there
    a better test?

  2. Not that I know. But why whould you want a better test? Minimising
    reflections is what it's all about, so IMO that's the only test you need.

    Get a spot of nose-grease on it, and see how difficult it is to make that
    area as dark (non-reflective) as the rest of the filter again. No better
    test.
