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 and 1.8 stop densities. Higher densities can be achieved by stacking two or more filters.
High-Quality Construction
Schneider solid color filters feature crystal clear, water-white optical glass, protected against edge-chipping and delamination by Schneider's unique Edge Seal, which also significantly reduces edge reflections and flare
Schneider Quality Control
Schneider filters are ground and polished to a precise flatness and plane parallelism
Because all Schneider filters are designed and manufactured with the highest possible degree of consistency, you can swap like filters mid-shoot with no discernible variation in color or effect.
Schneider Optics has engineered a major improvement in motion picture and broadcast television image quality with the Schneider filter line. Diamond cut from crystal-clear, water-white optical glass, Schneider filters are ground and polished to a precise flatness and planeparallelism (the exact parallel relationship between the front and back filter surfaces that is so important to optical performance). Then, to ensure perfection, this is verified by a laser interferometer. Schneider filters are also checked with a densitometer for consistent density, and tested for proper light transmission with a spectrophotometer. Because all Schneider filters are designed and manufactured with the highest possible degree of consistency, you can swap like filters mid-shoot with no discernible variation in color or effect. The unprecedented purity, color saturation and repeatability of Schneider filters virtually eliminate the need for lab color timing corrections caused by other filters. This puts more creative control where it belongs,
in your hands

Schneider came though for us with some of the first sets of their great new Platinum IRNDs, and all our color matching problems disappeared.

TIP HOW TO
PROLONGING
THE LIFE OF YOUR FILTERS
Filters, like all crafted optics, are susceptible not only to breakage, but to premature aging caused by environmental factors. Most filters are made up of several layers of materials consisting of glass, dyes, optical cements, chemical compounds, particles etc. Even with protective measures employed, there are many factors that can still affect the longevity of the filter: moisture (
prolonged
exposure to humidity), excessive heat and excessive light are the most common environmental causes that can affect the filter’s chemistry over time.
To protect your filters and keep them in great working condition for a long time (along with the rest of your camera gear) we recommend making sure to keep the filters stored in a dark, cool, and dry place when not in use. The use of filter pouches or specialized cases will also keep your filters safe from breakage when not in use. If you are in a humid environment, the addition of fresh silica gel packs or a dehumidifier in the room they are stored is also highly recommended. Protecting your filters as you would your camera lenses will ensure many years of use of your filters.
What do you recommend cleaning filters with?
Hand blower first, if it's just light dust, that usually handles it.
If you need to clean further, a Kim Wipe sprayed with Tiffen/Pancro Lens Cleaner, work in a circular motion from the middle out.
