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.
Schneider-Kreuznach RHOdium® FSND filters answer the cinematographer’s call for a truly neutral ND that attenuates light evenly from the near ultra-violet (important for a film) through the full visible spectrum and into the near infra-red. Our filters are manufactured to finer flatness/ parallelism specifications than ever before. These new filters help resolve even the finest detail.
Schneider-Kreuznach has engineered an extremely thin neutral density interlayer laminated between two sheets of crystal-clear water-white glass. Additionally, the coating is kept safe from abrasions by being encapsulated within the glass, rather than on the surface.
RHOdiums® are the first filters to undergo a lab-tested tristimulus scan, a more critical colour measurement than methods previously used to measure filter quality. This method verifies neutrality by utilizing a colourimetric algorithm that compares samples to perfectly neutral light. The result is unprecedented accuracy.
