What is near-infrared?
What is near-infrared?
Near-infrared light generally refers to light within the wavenumber range of 12,500 to 4,000 cm-1 (wavelengths from 800 to 2,500 nm) (see Fig. 1). Absorption of near-infrared light, like that of mid-infrared light, is based on the vibration of the material.
What is NIR used for?
NIR spectroscopy can be used for product identification, classification and quality control, as well as for the determination of product properties (chemical and physical) and component concentrations in process applications, all with the object of rapid analysis.
Is near-infrared sauna safe?
In general, infrared saunas are considered safe for most people. However, if you’re on medications, have implanted medical devices, or have a medical condition — whether acute or chronic — you should be cautious.
Which is better far or near infrared?
Near infrared units tend to promote topical healing and mild pain relief quite effectively, but far infrared heating units are incredibly effective at removing toxins, improving circulation, and relaxing the muscles.
Is red light therapy the same as near infrared?
Red light therapy (RLT) is a treatment that may help skin, muscle tissue, and other parts of your body heal. It exposes you to low levels of red or near-infrared light. Infrared light is a type of energy your eyes can’t see, but your body can feel as heat. Red light is similar to infrared, but you can see it.
Which is better far or near-infrared sauna?
Compared to near infrared wavelengths (which effectively penetrate and heal the skin) and far infrared wavelengths (which reach deep into the body, where toxins are stored), mid infrared wavelengths are longer than NIR, thus allowing for greater penetration into soft tissue.
How does NIR sensor work?
NIR-based sensing provides machines with information about objects in the physical environment. When NIR light is emitted and reflected off of an object, an NIR sensor receives the reflected light or light pattern to gauge the distance, size, location, and identifying features of objects in the three-dimensional world.
What does near infrared mean?
The near infrared (NIR) comprises low frequency radiation adjacent to red hues in the visible. The brightness we see in the NIR is due to reflected sunlight; not to temperature as many people, including some professionals, mistakenly believe.
Is near infrared good or bad for skin?
Using a near infrared sauna or a full spectrum infrared sauna (which also outputs near infrared) can cause cataracts, accelerated aging of the skin, and an increased risk of skin cancer.
Is near infrared bad for Your Eyes?
Scientists have found only wavelengths under 3000nm (near and mid infrared) to cause this damage to the eye. Shorter wavelengths, 780um to 1400nm (near infrared), are the most damaging. Wavelengths over 3000nm (far infrared) have never been shown damage the eye.
What is the difference between infrared and near infrared?
Detoxification. You can detoxify your body whether you use a near infrared or far infrared sauna.
