3-band multiband filter isolating Green (548 nm), Red (660 nm), and NIR (851 nm) in a single optic — replacing multiple discrete filters for streamlined optical paths and reduced insertion loss.
MBP-A35 Multiband delivers Centre / Range 548 nm (534 – 563 nm), Bandwidth (FWHM) 29 nm, and Peak transmittance ≥ 91.6 % 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 3-band design eliminates the need for a motorised filter wheel, reducing mechanical complexity and increasing acquisition speed
MBP-A35 transmits three narrow, sharply defined passbands at green, red, and near-infrared wavelengths while driving everything between and around them below 5 %. The first band spans 540–560 nm with Tavg above 86 % and a peak of 91.6 %. The second band covers 650–670 nm with Tavg above 89.6 % and a peak of 92.7 %. The third and brightest band occupies 830–870 nm with Tavg exceeding 90.9 % and a peak of 96.5 %. Between bands, blocking is deep: Tavg < 5 % from 350–520 nm, 580–630 nm, 690–810 nm, and 890–1050 nm. This triple-band architecture enables simultaneous three-channel detection from a single filter element.

MBP-A35 is a Triple-Band Bandpass Filter - Green + Red + NIR. MBP-A35 transmits three narrow, sharply defined passbands at green, red, and near-infrared wavelengths while driving everything between and around them below 5 %. The first band spans 540-560 nm with Tavg above 86 % and a peak of 91.6 %. Common uses include Multicolour fluorescence microscopy, Multispectral remote sensing and NDVI, Flow cytometry, and Machine vision with tri-band illumination.
Key published specs for MBP-A35 include Centre / Range: 548 nm (534 – 563 nm); Bandwidth (FWHM): 29 nm; Peak transmittance: ≥ 91.6 % T; Centre / Range: 660 nm (640 – 680 nm); Bandwidth (FWHM): 40 nm.
MBP-A35 is commonly used for Multicolour fluorescence microscopy, Multispectral remote sensing and NDVI, Flow cytometry, and Machine vision with tri-band illumination. Multicolour fluorescence microscopy - simultaneously detects green (GFP/FITC), red (Cy3/TRITC), and NIR (Cy5.5/ICG) fluorophores on a single camera exposure.
