B+W UV-IR Cut Filter Cut 486 MRC Basic 77 mm

The B+W 486 UV/IR Cut Filter features steep absorption against unwanted UV and infrared components. In digital cameras, where the IR filter before the image sensor has residual transmission, it prevents color casts and blurriness. This is achieved not through absorption via glass coloration, but through interference, using a multitude of ultra-thin partially reflective layers of precisely calculated thickness. The B+W 486 UV/IR Cut Filter is colorless and clear, requiring no exposure extension. It can also be permanently left on the lens as a protective filter. The B+W 486 UV/IR Cut Filter is MRC coated.
