Schneider 4x5.65" RHOdium Full Spectrum ND FSND Filter 2.4

Advanced Neutral Density for High-Resolution Sensors

The Schneider-Kreuznach RHOdium Full Spectrum Neutral Density (FSND) filters are engineered to meet the rigorous demands of 4K, 6K, and 8K digital cinematography. As modern sensors become more sensitive, managing IR leakage in the far-red and near-infrared spectrum is critical. The RHOdium series provides a truly neutral solution that attenuates light evenly across the entire spectrum.

Unmatched Color Neutrality

RHOdium filters are the first in the industry to undergo a lab-tested tristimulus scan. This advanced colorimetric algorithm compares filter samples against perfectly neutral light, ensuring a level of accuracy that traditional measurement methods cannot match. The result is a filter that maintains the integrity of your color palette without the shifts often associated with high-density NDs.

Durable Laminated Design

To ensure longevity and performance in the field, Schneider-Kreuznach utilizes a unique construction process:

• Encapsulated Coating: The thin ND interlayer is laminated between two sheets of crystal-clear water-white glass.
• Abrasion Resistance: Because the coating is internal, it is protected from scratches and environmental wear.
• Optical Precision: Finer flatness and parallelism specifications help resolve the micro-details required for large-format sensors.

The 2.4 density provides an 8-stop reduction in light, giving cinematographers greater control over depth of field and exposure settings in extremely bright environments without sacrificing image quality.
