Schneider 4x5.65" RHOdium Full Spectrum Neutral Density FSND 1.2 Filter, 4 Stop

How the Schneider RHOdium Full Spectrum Neutral Density (FSND) filters revolutionize the world of photography and cinematography is truly remarkable. These high-quality, durable filters are specifically designed to meet the critical color standards of advanced 4K, 6K, and 8K resolution cameras.

With the significant advancements in 4K, 6K, and 8K digital sensors, issues with IR leakage have been significantly reduced compared to older digital cameras. However, these state-of-the-art imaging sensors can still experience IR leakage within the far-red component of the visible spectrum, as well as the near IR. This is where the Schneider RHOdium FSND filters come into play, effectively controlling the IR within the full visible spectrum and into the near infra-red, especially at optical densities of 1.2 and higher.

These professional-grade filters are manufactured to the finest flatness/parallelism specifications, ensuring they can resolve even the finest detail. Schneider has ingeniously engineered an ultra-thin neutral density interlayer, sandwiched between two sheets of crystal-clear Schott water-white glass. This design results in superior transmitted wavefront flatness/parallelism, while also protecting the coating from abrasions by encapsulating it between the glass sheets, ensuring it can withstand the rigors of the rental market.

RHOdium FSND filters are the first of their kind to undergo a lab-tested tristimulus scan, a more stringent color measurement method than previously used. This method verifies neutrality by using a colorimetric algorithm that compares samples to perfectly neutral light, resulting in unprecedented accuracy.

Whether you're a cinematographer or a photographer working with the latest digital image capture technology, or even traditional film, the Schneider RHOdium FSND filters are an effective solution for all your Neutral Density needs, keeping the visible spectrum completely under control.

In the realm of physics, the Greek letter rho symbolizes the unit of Optical Density. Rhodium, a component of the "Platinum Group of Metals" on the periodic table of the elements, is a fitting namesake for these reliable, high-performance filters.
