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.
