Hi David/Ortega,

I am a PhD student and am working on integrating a wireless fNIRS system with other measurement methods for applications in alzheimer's disease and dimentia prevention and treatment. I am making a ninjaNIRS 2020 protoype but as I checked the NinjaNIRS 2020 site, there is no BOM list for dual optode module except component list in the Optode Assembly Document (Table 1). However, I am struggling in searching these component based on the information provided, especially components with the part number begins with BZB-. It looks like these components have internal part number instead manufacture part number.

Could you please provide or suggest the sites that I can search and order components for dual optode module, especially optical components?

In addition, is there update about the uploading plan of the ninjaNIRS 2021 to opennirs site?

Many thanks!

Hi, 

The components for NinjaNIRS 2021 will start appearing on the site next week with all design and production documents on the site by the end of January. I will find the BOM for the 2020 optode PCBs and attach it here when I get it. The two PCBs that are in the optode are custom manufactured but all components on the boards are off the shelf and can be purchased through digikey or mouser stock permitting. The light pipes are standard acrylic optical fiber and are cut down and polished to the lengths specified in the optode assembly protocol. The optical filter on line 8 of table 1 is a kodak wratten 2 No. 70 filter cut to size with the detector.

Digikey links to the the PIN photodiode we used:
