Description

BP470 filter enhance viewing of subjects illuminated by blue LED lighting and any UV-excited blue fluorescence emissions (430-500 nm). Its broad bandwidth and high peak (T >90%) transmission results in significantly brighter, higher contrast images. For most machine vision UV fluorescence applications, use of a BP470 filter is absolutely necessary.
