film holders are designed for use with no glass other than the platen.

holder glass and then AN glass on top. In most instances this will solve
your Newton ring problems. We've tested this technique at up to 4000 dpi
with no apparent image degradation.
modern film emulsions are so thin that two sheets of AN glass are
needed. But, this will
most likely limit the resolution of your scan. Customers have noticed in
scans much over 1500 dpi that they begin picking up the texture of two
sheets of AN glass.
if you want to cover all bases you can purchase both the bottom and top
sheets of AN glass just in case. But,
for most instances the single top sheet will work just fine.
