Filter—B+W 489 Infrared Cut

Last updated 2010-01-09 - Send Feedback
Related: filters, infrared

Spectral transmission graphs on this page were measured by Coastal Optical Systems on their equipment using single samples of the specified filters. Graphs used by permission.

Graphs are in nanometers. Visible light is approximately 390 - 650 nm (the human eye can see very weakly into the 700-800nm range).

Buying filters

A great source for filters at competitive prices is our trusted sponsor, B&H Photo. Get filters at B&H Photo.

Spectral transmission — B+W 489 infrared cut

No so effective at blocking infrared, with a very gradual “tail” well into the infrared range, passing nearly 50% infrared at 700nm.

This leakage is enough infrared to cause a red shift on IR-sensitive cameras like the Nikon D2H. It also passes shorter wave ultraviolet almost unimpeded.
