Used Schneider 4x5.65" True-Cut 750 IR Filter

Schneider Optics developed its True-Cut IR 750 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 750 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 Optics professional filters, the True-Cut IR 750 filter is manufactured from crystal clear, water white optical glass that is diamond cut, precision ground and polished to the most exacting tolerances.
