Measuring 6 x 4.8 x 1.1 mm each, IRR60-48C/TR8 SMT Infrared Emitting Diode, together with PD60-48C/TR8 PIN Photodiode feature optimized wavelengths of red 660 nm and infrared 905 nm, enabling accurate oximeter diagnosis. Infrared 905 nm can also be customized upon request to 940 nm or 910 nm. Both IRR60-48C/TR8 and PD60-48C/TR8 are discrete designs which allow feasibility on use, no matter if oximeter requires transmission or reflective design.
