Ikan
The Ikan NIR-OB-67 filter is a NiSi VARI ORange & Blue polarizer mounted on a 67 mm bracket.
These polarizers work as a variable ND filter, but instead of reducing all light evenly, these filters specifically target the orange and blue wavelengths and depending on the settings, users can get to remove these colors from the light of photos and videos.
NIR-OB filters also function as a standard polarizer, cutting light from non-metallic reflected surfaces and changing the light transmission of digital displays.
Each piece of glass has a two-sided, multilayer anti-glare coating, and the color film ensures that the color and image at the edges will not fade or distort.
