NiSi Polarizer 4 × 5.65″ is a rectangular linear polarizing filter with AGC glass and Nitto polarizing film (99.9%). Filter factor is 2–2.8, i.e. 1–1.5 stops, thickness 4 mm.
To set polarization, insert it into a rotating matte box slot. The linear type suits digital cine cameras; for cameras with a beam-splitter prism, choose a circular polarizer.
