B+W 86mm 486 Digital UV/IR Blocking Glass Filter

This B&W 86mm 486 Digital UV/IR Blocking Glass Filter has a completely colorless glass carrier coated with a number of extremely thin, partially reflecting layers with precisely computed thicknesses, similar to MC coating (multi-coating).

The B&W 486 Filter is not an "absorption" filter. It interferes with unwanted UV and IR radiation which affects the wavelengths of both ends of the visible spectrum. The disruption occurs when these two variables scatter between each other and cause a drop-off effect.
