470nm Blue Bandpass Filter

Bandpass Filter

Description:

470nm 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 470nm 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. 470nm is also frequently used in 3D measurement applications.
