The Schneider Optics True-Cut IR 680 is similar to the True-Cut 750 except that it blocks light at the very edge of the visible spectrum for certain high definition cameras that require extra IR blocking to achieve true black tones. Some cameras that can take advantage of the extra IR blocking abilities of the True-Cut IR 680 are the Sony PMW-EX1 and PMW-EX3.
Most high-definition cameras have a high sensitivity to light in the IR spectrum, and though the IR light is not visible to the human eye, it can result in odd color shifts and prevent a camera’s imagers from capturing true blacks. As digital cinematographers use multi-stop neutral-density (ND) filters to allow them to open their lens iris for more depth of field, IR light begins to dominate light from the visible spectrum, making its pollution all the more apparent.
Schneider, a world leader in precision optics for nearly a century, developed its True-Cut IR 680 filter to remove the IR spectrum from the light path, resulting in more vibrant colors and true blacks from both CCD and CMOS imagers. The True-Cut IR filter blocks the IR light mere nanometers from the visible spectrum, eliminating IR pollution from the image.
The True-Cut IR 680 filter maintains a high MTF (modulation transfer function) in the visible spectrum and its coating meets or exceeds military standards for durability, thus is easily cleaned. Like all Schneider professional filters, the True-Cut IR 680 filter is manufactured from crystal clear, water white optical glass that is diamond cut, precision ground and polished to the most exacting tolerances.
True-Cut IR 680 filters are available in standard sizes, including: 4x4, 4x5.65, 5x5, 5.65x5.65, 6.6x6.6 rectangular sizes plus rounds including 138mm, 4.5” and Series 9.
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.
