Hi folks!

I'm really struggling to find any available bi-color LED emitters in the NIR wavelength spectrum. Does anyone know where to source them in small amounts? I'm trying to order parts, but I'm pretty much stuck until I can find these. I can't find them on Digikey or Mouser. Any help would be greatly appreciated πŸ™‚

I've had success in the past with Marubeni, but they don't always have stock, and if they don't they require a large order to manufacture more.

I agree with Antonio. It also depends on what you mean with small amounts.

Digikey has some of the Marktech offerings, but they are quite expensive and low power.

Thank you so much! By small amounts, I mean less than 5.Β 

For context: I'm a student trying to get a working fNIRS system off the ground, so I can hopefully contribute to this project.
