| Name: Schneider 4X5.65 True-Cut IR Filter Part Number: 366037 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 TRU-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 TRU-CUT IR filter blocks the IR light mere
nanometers from the visible spectrum, eliminating IR pollution from the
image.
The TRU-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 professional filters, the TRU-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. |
