Short-Wave Infrared emitters produce infrared waves of around 0.75 – 1.4 microns in wavelength and operate at high temperatures above 1,300 – 2,6000C. Since these wavelengths have higher frequencies, they tend to be more transmissive and reflective.The high efficiency of this technique, however, not only follows from the absorption properties of the materials to be heated, but also in conjunction with the atmosphere.
