2-band multiband filter isolating Yellow (587 nm) and NIR (884 nm) in a single optic — replacing multiple discrete filters for streamlined optical paths and reduced insertion loss.
MBP-A48 Multiband delivers Centre / Range 587 nm (462 – 712 nm), Bandwidth (FWHM) 250 nm, and Peak transmittance ≥ 94.6 % T.
The hard-oxide coating is built for repeated handling, heat, and cleaning.
Best suited for:
Multi-spectral imaging systems that require simultaneous capture across visible and near-infrared channels — this 2-band design eliminates the need for a motorised filter wheel, reducing mechanical complexity and increasing acquisition speed
MBP-A48 transmits two broad, high-throughput windows – one spanning the visible spectrum from 475 nm to 690 nm and a second in the near-infrared from 850 nm to 910 nm – while blocking everything outside. The visible passband delivers Tavg above 93.3 % with a peak of 94.6 %, covering the full green-to-red range. The NIR passband holds Tavg above 93.9 % with a peak of 95.3 %, centred on the 880 nm region widely used in sensing applications. Blocking is deep: Tavg < 3 % from 300–435 nm (UV-blue), < 3 % from 750–780 nm (inter-band gap), and < 3 % from 1000–1100 nm (extended NIR). The result is a clean dual-band filter that lets through the visual scene and a discrete NIR channel with minimal cross-contamination.

MBP-A48 is a Dual-Band Bandpass Filter - Visible + NIR (475-690 nm and 850-910 nm). MBP-A48 transmits two broad, high-throughput windows - one spanning the visible spectrum from 475 nm to 690 nm and a second in the near-infrared from 850 nm to 910 nm - while blocking everything outside. The visible passband delivers Tavg above 93.3 % with a peak of 94.6 %, covering the full green-to-red range. Common uses include Day-night vision systems, Precision agriculture and NDVI drones, Security and surveillance cameras, and Autonomous driving sensor fusion.
Key published specs for MBP-A48 include Centre / Range: 587 nm (462 – 712 nm); Bandwidth (FWHM): 250 nm; Peak transmittance: ≥ 94.6 % T; Centre / Range: 884 nm (841 – 927 nm); Bandwidth (FWHM): 86 nm.
MBP-A48 is commonly used for Day-night vision systems, Precision agriculture and NDVI drones, Security and surveillance cameras, and Autonomous driving sensor fusion. Day-night vision systems - transmits a full-colour visible image during the day and an 850 nm NIR channel for active illumination at night, all through a single filter.
KUPO lists the construction for MBP-A48 as Ion-assisted hard-oxide; 5 – 450 mm shapes, 0.21 – 3.8 mm thick.
