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.
