Figure Lengend Snippet: Fluorescence of the test photographic filters normalized to Schott KV-418. Bar color indicates the color of the filter fluorescence.

Article Snippet: The Schott KV-418 filter shows a gradual cutoff starting at about 405 nm ( a) and then rising through 50% maximum transmission at approximately 418 nm as expected.
