BP470-49 | BP470 Blue Bandpass Filter

The MidOpt BP470-49 filter enhances the viewing of subjects illuminated by blue LED lighting and any UV-excited blue fluorescence emissions (430-500nm). Its broad bandwidth and high peak transmission (T ≥90%) result in significantly brighter, higher-contrast images. For most machine vision UV fluorescence applications, the use of a BP470 filter is absolutely necessary. The StablEdge design prevents unwanted interference from lighting used 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.
