Description

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.

Key Advantages

  • Three discrete passbands at green (540–560 nm), red (650–670 nm), and NIR (830–870 nm) - enables simultaneous tri-channel detection without filter-wheel swaps or beam splitters.
  • Deep inter-band blocking with Tavg < 5 % - suppresses cross-talk between channels, yielding high colour purity and spectral contrast.
  • NIR peak at 96.5 % - maximizes signal strength in the critical 850 nm sensing band used by LiDAR, pulse oximetry, and vegetation indices.
  • Hard-oxide durability - ion-assisted coating resists heat, humidity, solvents, and repeated cleaning.
  • Custom formats available - round, square, or free-form blanks from 5 mm to 450 mm, thickness 0.21–3.8 mm, on Borofloat®, soda-lime, Schott D263 T, or Corning Eagle XG substrates.

Typical Applications

  • Multicolour fluorescence microscopy - simultaneously detects green (GFP/FITC), red (Cy3/TRITC), and NIR (Cy5.5/ICG) fluorophores on a single camera exposure.
  • Multispectral remote sensing and NDVI - captures the green, red, and NIR reflectance bands required for Normalized Difference Vegetation Index and crop-health analysis.
  • Flow cytometry - enables three-colour sorting with a single detector path, reducing instrument complexity and increasing throughput.
  • Machine vision with tri-band illumination - pairs with matched LED sources at 550 nm, 660 nm, and 850 nm for simultaneous multi-wavelength inspection.
  • Biomedical imaging - passes the green, red, and NIR wavelengths used in photoplethysmography, tissue oxygenation mapping, and endoscopic imaging.
