BP450-77 | BP450 Indigo Bandpass Filter

The MidOpt BP450-77 filter enhances the viewing of subjects illuminated by a 450nm blue LED or laser light source and any UV-excited blue fluorescence emissions (420-470nm). Its broad bandwidth and high peak transmission (T ≥90%) result in significantly brighter, higher-contrast images. For most machine vision UV fluorescence applications, a Bandpass filter is absolutely necessary.
