BP470 filters enhance viewing of subjects illuminated by blue LED lighting and any UV- excited blue fluorescence emissions (430-500nm). 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. The StablEdge design prevents unwanted interference from lighting employed for UV excitation (365-405nm) even when the filter is used in conjunction with short focal length, wide angle lenses. BP470 is also frequently used in 3D measurement applications.
