Hi everyone,

Im looking for SMD leds with red and infrared wavelenghts. Both in a single package. It's to be used in a pulse oxymeter.

Do you know a company that offers this kind of LED/packages? In other words, do you know where to buy leds for pulse oximeters?

Any suggestion would be greatly appreciated.

Thanks

Why not two teeny LEDs right next to each other?
