Filter—B+W 415 and 420 UV Cut

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 — B+W 415 and B+W 420 UV cut.

See also the Schneider B+W filter handbook.

The B+W 415 has a faint yellow tint, and blocks all UV light, and a trace of violet light (hence the pale yellow color). It is a very strong UV filter.

The B+W 420 is even stronger thant the B+W 415, and cuts off visible violet light as well.

This filter is special order.
