NISI CINEFILTER POLARIZER
NISI lineært polarisationsfilter er et effektivt polariserende filter til film-, TV- og videokameraer. Det hjælper med at reducere refleksioner og genskin ved at bortfiltrere lys, som er blevet polariseret på grund af refleksioner fra en ikke-metallisk overflade. Dette resulterer i en mærkbar reduktion af reflekser fra f.eks. metal-, vand- og glasoverflader og giver større mætning i himmel og løvhang.
Det er produceret ved hjælp af en proces, som indebærer laminering af et lag af polariserende film mellem 2 optiske glas. Glaslaget slibes derefter fladt for at bibeholde den maksimale billedskarphed.

The NiSi Linear Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.
A linear polarizer differs from a circular polarizer in that it does not contain an additional quarter wave plane. The addition of a quarter wave plane is to circularly polarize linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, in-camera auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.
