Infrared radiation is in the form of heat transfer and heat transfer, energy by electromagnetic waves. When in the far-infrared radiation to the object to be heated, some radiation is reflected back, partly through the past. When launching far infrared wavelength and the absorption wavelength of the object to be heated when heated objects absorb far infrared, and Interior molecules and atoms "resonance" – strong vibrations, rotating and vibrating and rotating the body temperature, achieve the purpose of heating.
0.7um-80um refers to the spectrum of infrared radiation between the emission and transmission of electromagnetic waves (transmitted), emission and transmission along with clear, directional energy transmission, transmission of energy without a medium of Exchange, can be transmitted even in a vacuum. Infrared light according to wavelength can be divided into short wave, medium wave, long wave.
