B+W UV-IR CUT 486 MRC BASIC 82mm

B+W UV-IR SPERR-FILTER CUT 486 MRC BASIC 82 mmThe B+W 486 UV/IR blocking filter has steep-angle absorption against unwanted UV and infrared components.It prevents color casts and blurring in digital cameras whose IR blocking has residual transmission in front of the image sensor. This is not achieved by absorption via glass coloring, but by interference, a multitude of extremely thin partially reflecting layers of precisely calculated thickness.The B+W 486 UV/IR blocking filter is colorless clear and requires no exposure extension.It can also be left permanently on the optics as a protective filter. The B+W 486 UV/IR blocking filter is MRC coated.
