Hutchinson Technologies


The technology platforms used to develop HTI's medical device products include optical metrology, and specifically, near infrared spectroscopy. Coupled with HTI's world leadership in precision engineering, these technologies provide a powerful foundation for innovation in health care.

Near Infrared Spectroscopy

Near infrared spectroscopy (NIRS) uses specific, calibrated wavelengths of near infrared light to noninvasively illuminate the tissue below a sensor placed on the skin. (more)

NIRS and the InSpectra™ StO 2Tissue Oxygenation Monitor

The InSpectraStO 2 Tissue Oxygenation Monitor works by sending light through the skin into underlying tissues and taking measurements of the light after it travels through the tissues. (more)

StO2: Tissue Oxygen Saturation

StO2 is the quantification of the ratio of oxygenated hemoglobin to total hemoglobin in the microcirculation of the volume of illuminated tissue, and is an absolute number. (more)
