2-band multiband filter isolating Red (656 nm) and NIR (874 nm) in a single optic — replacing multiple discrete filters for streamlined optical paths and reduced insertion loss.
MBP-A60 Multiband delivers Centre / Range 656 nm (606 – 706 nm), Bandwidth (FWHM) 100 nm, and Peak transmittance ≥ 95.6 % 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-A60 transmits two narrow, high-throughput windows centred on the deep red and near-infrared regions. The first passband spans 630–690 nm with Tavg above 93.6 % and a peak of 95.6 %, targeting the deep-red emission range. The second passband covers 850–910 nm with Tavg above 94.3 % and a peak of 95.4 %. Outside these windows, blocking is aggressive: the entire UV-to-green range (300–596 nm) is held below 5 %, the inter-band gap (720–809 nm) sits below 5 %, and the extended NIR beyond 947 nm drops below 5 %. This two-channel architecture isolates the specific wavelength pairs used in blood-oxygen monitoring, vegetation sensing, and targeted fluorescence detection.

MBP-A60 is a Dual-Band Bandpass Filter - Deep Red + NIR (630-690 nm and 850-910 nm). MBP-A60 transmits two narrow, high-throughput windows centred on the deep red and near-infrared regions. The first passband spans 630-690 nm with Tavg above 93.6 % and a peak of 95.6 %, targeting the deep-red emission range. Common uses include Pulse oximetry and SpO2 sensors, Photoplethysmography (PPG) wearables, Precision agriculture and red-edge sensing, and Fluorescence-guided surgery.
Key published specs for MBP-A60 include Centre / Range: 656 nm (606 – 706 nm); Bandwidth (FWHM): 100 nm; Peak transmittance: ≥ 95.6 % T; Centre / Range: 874 nm (824 – 923 nm); Bandwidth (FWHM): 99 nm.
MBP-A60 is commonly used for Pulse oximetry and SpO2 sensors, Photoplethysmography (PPG) wearables, Precision agriculture and red-edge sensing, and Fluorescence-guided surgery. Pulse oximetry and SpO2 sensors - passes the 660 nm (deoxyhemoglobin) and 880 nm (oxyhemoglobin) wavelengths that form the basis of blood-oxygen saturation measurement.
