RHOdium FSND Filters are available in 4X5.65 and 6.6X6.6 sizes in 10 stops from 0.3 – 3.0. This is the .3 FSND sized at 4x5.65.

The Schneider RHOdium Full Spectrum Neutral Density (FSND) filters are a high-end ND filter line made specifically for the critical color standards of 4K, 6K, and 8K resolution cameras.

Major advancements in 4K, 6K and 8K digital sensors have resulted in fewer issues with IR leakage compared to digital cameras of the past. However, these imaging sensors can still be subject to IR leakage within the far-red component of the visible spectrum, as well as the near IR. IR absorption continues to be a requirement, because of this. This is particularly true at optical densities of 1.2 and higher. Schneider’s RHOdium FSND filters answers the cinematographer’s call for a truly neutral ND which controls the IR within the full visible spectrum and into the near infra-red.

RHOdium FSND filters are manufactured to finer flatness/parallelism specifications than ever before. These new filters help resolve even the finest detail. Schneider has engineered an extremely thin neutral density interlayer sandwiched between two sheets of crystal-clear Schott water-white glass. The thin interlayer results in excellent transmitted wavefront flatness/parallelism. Additionally, the coating is kept safe from abrasions by being encapsulated between the glass, rather than on the surface, so it can withstand the rigors of the rental market.

RHOdiums are the first filters to undergo a lab-tested tristimulus scan, a more critical color measurement than methods previously used to measure filter quality. This method verifies neutrality by utilizing a colorimetric algorithm that compares samples to perfectly neutral light. The result is unprecedented accuracy.

Cinematographers and photographers working with the latest in digital image capture technology, or even with film, will find the FSND filters wonderfully suited for all of their Neutral Density needs by keeping the visible spectrum completely in control.

Wondering about the RHOdium filter line name? In physics, the Greek letter rho "ρ" represents the unit of Optical Density. Rhodium, is a component of the "Platinum Group of Metals" on the periodic table of the elements.
