EVERLIGHT ELECTRONICS has introduced an IR emitting diode in a miniature SMD package and a high speed, high sensitive PIN photodiode. Both measuring 6x4.8x1.1mm for oximeter detector applications, the IRR60-48C/TR8 IR emitter and the PD60-48C/TR8 PIN photodiode feature optimised red and IR wavelengths of 660 and 905nm, respectively.
According to past experience, red 660nm together with infrared 905nm appear best to detect the oxygenation of the blood which provides accurate diagnosis on oximeters.
Upon request, the infrared 905nm can also be customised to 940 or 910nm. Both IRR60-48C/TR8 and PD60-48C/TR8 are discrete designs which are suitable for oximeters, regardless of transmission or reflective design requirements. Both products are RoHS-compliant.
