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 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 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 filter is manufactured from crystal clear, water white optical glass that is diamond cut, precision ground and polished to the most exacting tolerances.
