Bi-color SMD leds: red and infrared?

Started by msr March 15, 2011
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? -- Tim Wescott Wescott Design Services http://www.wescottdesign.com Do you need to implement control loops in software? "Applied Control Theory for Embedded Systems" was written for you. See details at http://www.wescottdesign.com/actfes/actfes.html
