Schneider Optics offers new TRU-CUT IR-750 filter
November 17, 2008
Schneider Optics has introduced the TRU-CUT IR-750 filter, designed to eliminate light in the infrared (IR) spectrum before it reaches an HD camera’s sensors.
Most HD 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 videographers 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 apparent.
Schneider developed 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 is manufactured from white optical glass that is diamond cut, precision ground and polished to the most exacting tolerances. The filters are available in 4 x 4, 4 x 5.65, 5 x 5, 5.65 x 5.65, 6.6 x 6.6 rectangular sizes and 138mm, 77mm, 4.5in and Series 9 round sizes.
