Negative Supply Basic 4 x 5" Sheet Film Scanning Kit (Micro-Etched Acrylic)

The Negative Supply Basic 4 x 5" Sheet Film Scanning Kit (Micro-Etched Acrylic) (B&H# NEB45HLDRA) is also an anti Newton ring material. Both ANR glass and micro etched acrylic cause some diffusion. The degree of that diffusion depends on the particular ANR glass and micro etched acrylic involved; No universal comparison is possible. Using glass with mineral oil (or similar) between the negative and the glass on both sides (but not using ANR glass nor micro etched acrylic) would also work to prevent Newton rings, but most people do not want oily negatives. Such is the trade-off between preventing Newton rings and preserving the clarity of the image.
