PureLight Sensor from Nonin

PureLight Sensor Technology

PureLight® sensors produce a high-intensity pure light spectrum which eliminates variations in readings from patient-to-patient and sensor-to-sensor.

The PureLight Principle

Red and infrared light sources (LEDs) are essential to pulse oximetry sensors.

  • The red LED measures deoxygenated hemoglobin.
  • The infrared LED measures oxygenated hemoglobin

Common red LEDs may produce a secondary spectrum emission (contamination)

  • Contamination impacts the oxygenated hemoglobin measurement.
  • LED contamination shifts the oximeter»s calibration curve resulting in inaccurate SpO2 readings below 80%.
