Schneider 4x5.65" RHOdium Full Spectrum ND FSND Filter 3.0

Professional Neutrality for High-Resolution Cinematography

The Schneider-Kreuznach RHOdium Full Spectrum Neutral Density (FSND) filter is 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 visible spectrum and beyond.

Advanced Lamination and Optical Clarity

Each filter features an ultra-thin neutral density interlayer encapsulated between two sheets of premium water-white glass. By laminating the coating within the glass rather than applying it to the surface, Schneider-Kreuznach ensures the ND layer is protected from abrasions and environmental wear. This construction also maintains exceptional flatness and parallelism, essential for resolving fine details in high-resolution productions.

Tristimulus Scan Technology

RHOdium filters are the first to be verified using a lab-tested tristimulus scan. This advanced colorimetric algorithm compares the filter performance against perfectly neutral light, ensuring unprecedented color accuracy. The result is a consistent, predictable image that simplifies color grading and maintains the integrity of your creative vision.
