Near infrared is the region within the infrared spectrum that is close to visible light. It is widely used in many industries, particularly in the medical field where its accuracy can help save one’s life. Exactly how does near infrared work to become a valuable asset in daily life?

 

Here is what many people know: you can only see seven colors in a rainbow. Any color above violet can hurt your eyes big time, while any hue below red is as invisible as a ninja. Infrared is the region close to visible light, meaning near infrared is even closer. You may not see the thing with your eyes, but you only have to know that it exists, helping in the continued survival of the human race.

 

Take any matter you want to test and let the near infrared machines dish out spot-on results. A near infrared machine works by simply emitting near infrared energy at the material, taking note of what the near infrared energy is stumbling upon. The machine instantly returns with important data about the material: what it is made of and how much of one thing it contains.

 

This highly accurate gauge is ideal if you cannot get the exact amount of a substance by merely looking at it. Substances such as urine, soil, and petrol require a deeper look at the ingredients comprising that substance. Sometimes, you have to look beyond what your eyes normally see to get the clearer picture.

 

While various materials reflect incoming energy differently, a common trend is that reflectance is at its highest the longer the wavelength. In a reflectance test of three metals, they reflected the energy below 500 nanometers differently. However, they attained full reflectance at wavelengths that are more than a micron. At 0.78 to 2.50 microns in length, near infrared reflectance is at its highest with most substances.

 

With a high reflectance rate, near infrared machines can provide more accurate details about a substance’s composition. It is just like sending dozens of aerial drones to scout a wide area: the more drones return, the more data about the area. Indeed, near infrared energy is a key player in various sectors of daily life.
