Schneider 4x5.65" RHOdium Full Spectrum ND FSND Filter 0.9

Professional Neutrality for High-Resolution Cinematography

The Schneider-Kreuznach RHOdium Full Spectrum Neutral Density (FSND) filters are engineered to meet the rigorous demands of 4K, 6K, and 8K digital sensors. While modern sensors have improved IR handling, they remain susceptible to leakage in the far-red and near-infrared spectrums. The RHOdium series provides a truly neutral solution that attenuates light evenly across the entire spectrum from near-ultraviolet to near-infrared.

Advanced Lamination and Durability

Unlike traditional filters with surface coatings, Schneider-Kreuznach utilizes a specialized thin-film interlayer. This ND layer is laminated between two sheets of premium water-white glass, protecting the coating from abrasions and environmental wear. This construction ensures the filter maintains its performance and resolves the finest details throughout years of professional use.

Unprecedented Color Accuracy

RHOdium filters are the first to be verified via tristimulus scanning. This lab-tested method uses a colorimetric algorithm to compare light samples against a perfectly neutral reference. The result is a filter that eliminates color shifts, allowing cinematographers to maintain consistent skin tones and color palettes across different densities.
