Schneider 4x4 Platinum IRND Filter 1.8 (6-Stop)
Schneider’s new Platinum Series IRND filters limit the light striking the camera’s CCD or CMOS imager to the visible spectrum. By carefully calculating the cutoff frequency in nanometers, we have been able to produce a near-infrared cut filter that lets users of high definition cameras get the most out of their camera gear. This means the benefit of an extended color gamut without the worry of unwanted false colors. Eliminating the near-infrared light leakage lets the camera maintain true color rendition in the blacks while maintaining high MTF of its lenses and camera system.
Schneider Platinum Series IRND filters are free of off-axis color shift regardless of the focal length and can be stacked without introducing reflections common in dichroic filters. They can also be used as a standard ND filter with all HD video and film cameras. These filters are available in all standard video and cine sizes, including: 4x4, 4x5.65, 5x5, 5.65x5.65, 6.6x6.6 sizes plus rounds in 138mm, 4.5” and Series 9. This filter is available in 0.3, 0.6, 0.9, 1.2, 1.5, 1.8, and 2.1 stop densities. Higher densities can be achieved by stacking two or more filters.
