Schneider Optics Intros TRU-CUT IR-750 Filter
Optics introduces the TRU-CUT IR-750 filter, designed to eliminate light in the
infra-red (IR) spectrum before it reaches a High Definition camera’s sensors.
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
black tones. 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 more
its TRU-CUT IR-750 filter to remove the IR spectrum from the light path,
resulting in more vibrant colors and true black tones from both CCD and CMOS
sensors. The TRU-CUT IR filter blocks the IR light mere nanometers from the
visible spectrum, cutting 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
TRU-CUT IR-750 filters are available in standard sizes, including: 4×4, 4×5.65,
5×5, 5.65×5.65, 6.6×6.6 rectangular sizes plus rounds including 138mm, 77mm,
4.5” and Series 9.
