Diamond cut from crystal-clear, water-white optical glass, Schneider filters are ground and polished to a precise flatness and planeparallelism (exact parallel relationship between front and back filter surfaces). Then, to ensure perfection, this is verified by a laser interferometer. Schneider filters are then checked with a densitometer for consistent density, and tested with a spectrophotometer for proper light transmission. It's due to this ultra-high consistency, that allows cinematographers to swap like filters mid-shoot with no discernible variation in color or effect. What's more, the unprecedented purity, color saturation and repeatability of Schneider filters virtually eliminate the need for lab color timing correction.
