IR LED wavelength specification

Customer:

What is the wavelength of the IR LED you stock? The description mentions a spectrum that the human eye can’t see, which suggests 940nm, but I need 850nm.

Dobar dan, zanima me, kao što je napisano u naslovu, valna duljina IR LEDice koju držite. Pretpostavljam da je 940nm zato što u opisu piše “spectrum that the human eye can’t see”, dok je meni potrebna 850nm.

Hvala

Since this is a generic component, I don’t have exact specifications on hand. However, when I used it myself, I didn’t notice any hint of red light, so I believe it’s 940nm.

hvala na upitu, pošto je generička komponenta nemam točan podatak ali mogu ti reći da kad sam ja koristio nisam primijetio ni dašak crvene, tako da mislim da je riječ o 940nm.
