Why Wavelengths Matter
Within the near-infrared spectrum, each wavelength of light offers a window into the tissue, and each offers a unique perspective or view of what’s going on inside.
When looking for something as important as the oxygenation of the brain, FORE-SIGHT ensures you receive the most accurate view possible by interrogating the tissue using 5 different wavelengths. Alternative cerebral oximeters use as few as 2 wavelengths, using data from a narrow window in the NIR spectrum. By choosing several wavelengths throughout the NIR spectrum, FORE-SIGHT ELITE sees the whole picture. See the difference for yourself by using the slider on this page.
The curves in the charts above represent how these substances absorb NIR light. The closer the curves are to each other, the more they “appear” the same – the further they are apart, the more easily distinguishable they are from one another.
Not only does FORE-SIGHT ELITE utilize the most wavelengths of any tissue oximeter, the device is also the only oximeter to take advantage of the 690nm wavelength – a perspective of the tissue that allows for the greatest differentiation between oxy-and deoxygenated hemoglobin, melanin, and other background tissue properties.
With the best view into the brain, you have the confidence of knowing you are looking at an accurate picture of your patient’s tissue oxygenation status.
