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).

Spectral Transmission — Kenko IR block filter DR-655

See the Japanese language specification page describing this interference type filter. The spectral transmission curve suggests that color rendition might offer some irregularities.

The loss of blue (400-420nm) is substantial, and its uneven spectral transmission is not desirable. However, it cuts infrared off sharply at 650nm.

Compare to the B+W 486.
