BP Series - Broad Bandwidth - Bandpass Filters

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.

BP365 UV Blacklite dichroic filters can be used with all UV LED, UV fluorescent and other UV-producing lamp-based lighting. BP365  filter material is designed to block the visible and pass UV light, including 395nm and all other popular UV LED wavelengths.  It is also useful for near-UV fluorescence imaging, blocking visible light and light from … Continued

Useful in UV imaging applications, BP324 filters have a broad spectral bandwidth in the UV while effectively blocking most visible and infrared light. Note that there is a slight deep red/near IR leak that peaks at about 720nm. Because this filter absorbs all unwanted visible and/or infrared light, it is not recommended for placement in front … Continued

The BP250 filter is a very broadband UV filter, mainly intended for deep-UV imaging. It is the only MidOpt UV filter available that offers excellent visible and near-IR blocking., thus making it best suited to distinguish features or characteristics that are only visible under UV illumination. Offered in a limited number of sizes, and not … Continued
