3-band multiband filter isolating UV (350 nm), Green (520 nm), and NIR (966 nm) in a single optic — replacing multiple discrete filters for streamlined optical paths and reduced insertion loss.
MBP-A50 Multiband delivers Centre / Range 350 nm (343 – 356 nm), Bandwidth (FWHM) 13 nm, and Peak transmittance ≥ 70.7 % 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 3-band design eliminates the need for a motorised filter wheel, reducing mechanical complexity and increasing acquisition speed
MBP-A50 opens two wide transmission windows that together capture both the visible spectrum and a broad NIR band. The first passband spans approximately 410–610 nm with Tavg above 93.8 % and a peak of 95.2 %, covering the blue-through-orange visible range. The second passband runs from 870 nm to beyond 1100 nm with Tavg above 94.4 % and a peak of 95.9 %. Between the two windows, a sharp blocking zone drives Tavg below 1.5 % from 700–780 nm, cleanly separating the visible and NIR channels. The combination of broad visible coverage and extended NIR response makes MBP-A50 a versatile dual-band filter for day-and-night or visible-plus-NIR applications.

MBP-A50 is a Dual-Band Bandpass Filter - Visible + NIR (410-610 nm and 870-1100 nm). MBP-A50 opens two wide transmission windows that together capture both the visible spectrum and a broad NIR band. The first passband spans approximately 410-610 nm with Tavg above 93.8 % and a peak of 95.2 %, covering the blue-through-orange visible range. Common uses include Day-night surveillance and security cameras, Precision agriculture and multispectral UAV payloads, Autonomous vehicle perception, and Biomedical and clinical imaging.
Key published specs for MBP-A50 include Centre / Range: 350 nm (343 – 356 nm); Bandwidth (FWHM): 13 nm; Peak transmittance: ≥ 70.7 % T; Centre / Range: 520 nm (396 – 645 nm); Bandwidth (FWHM): 249 nm.
MBP-A50 is commonly used for Day-night surveillance and security cameras, Precision agriculture and multispectral UAV payloads, Autonomous vehicle perception, and Biomedical and clinical imaging. Day-night surveillance and security cameras - transmits full-colour visible during the day and switches to 850-940 nm NIR active illumination at night without swapping filters.
