Infrared usually use tungsten material to the lamp with luminous light. The distance between patients and device are 45 to 60 cm. The wavelength is 800 nm and perpendicular to the area of pain.

What is the range of infrared light?
Infrared radiation extends from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 millimeter (mm). This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz. Beyond infrared is the microwave portion of the electromagnetic spectrum.
How long are infrared light waves?
The infrared range is usually divided into three regions: near infrared (nearest the visible spectrum), with wavelengths 0.78 to about 2.5 micrometres (a micrometre, or micron, is 10–6 metre); middle infrared, with wavelengths 2.5 to about 50 micrometres; and far infrared, with wavelengths 50 to 1,000 micrometres.
What is far infrared rays?
Far-Infrared Rays are waves of energy, totally invisible to the naked eye, which penetrate the surface of the skin where they gently and elevate the body’s surface temperature to 107.6F/42C and above, whilst positively activating body systems and functions.
What is near IR and far IR?
Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. “Near infrared” light is closest in wavelength to visible light and “far infrared” is closer to the microwave region of the electromagnetic spectrum.
How is infrared light measured?
How to measure the infrared light? Visible light is measured in lux, such as 0.05 lux or 0.1 lux. However, infrared light cannot be measured in lux, because it is invisible. The most common way to measure infrared light is in watts/ M² or Ft², or the energy produced by an infrared light source over a specific area.
Are far infrared rays harmful?
IR light may cause thermal injury even if you do not feel pain for certain types of IR light exposure. Hyperpigmentation, scaling, and telangiectasias (erythema ab igne) may occur from repeated IR exposures of elevated temperatures, even if the skin is not burned. Skin cancer is not expected from exposure to IR.
How is far infrared generated?
Far Infrared is Safe – Your Body Generates it When our bodies are heated by FIR rays the activity level of our atoms are increased and heat can be generated. Our bodies radiate Far Infrared energy through the skin at 3 to 50 microns, with most output at 9.4 microns.
Where is far infrared?
Far-infrared radiation (FIR) is found on the wavelength spectrum at 15–1000 μm with a frequency range of 20 – 0.3 THz, and photon energy range of 83 – 1.2 meV.
Can you see far infrared light?
What are Infrared Waves? Infrared waves, or infrared light, are part of the electromagnetic spectrum. People encounter Infrared waves every day; the human eye cannot see it, but humans can detect it as heat.
Which is better far infrared 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.
How many nm is far-infrared?
Category 3: Far-Infrared This region has a wavelength range of 3,000 nm to 1 nm, or 3 to 1,000 microns and a frequency range of 0.3 THz to 20 THz. The far-infrared region has the shortest wavelengths and the longest frequencies, which produces the most heat.
What is the difference between infrared and far-infrared?
Near infrared saunas use infrared light that is closer to the visible spectrum. Far infrared saunas use infrared light that is further down the spectrum and not very visible to the human eye. Because of this, far infrared saunas can only reach about 5mm under your skin.
