Schneider-Kreuznach RHOdium® FSND filters answer the cinematographer’s call for a truly neutral ND that attenuates light evenly from the near ultra-violet (important for a film) through the full visible spectrum and into the near infra-red. Schneider-Kreuznach has engineered an extremely thin neutral density interlayer laminated between two sheets of crystal-clear water-white glass. Additionally, the coating is kept safe from abrasions by being encapsulated within the glass, rather than on the surface. (NOTICE: Filter product images are rendered examples. Actual product appearance and effect will vary.)
