9. Attention in the infrared rays use (Q&A)

(Q) Can heat in the far-infrared rays metal? (A) Since there is a lot of metal electrons, it reflects the electromagnetic waves (far-infrared rays) in general. The good conductivity metal such as gold and aluminum, it is hard to heating ...

8. Comparison of far-infrared rays and near-infrared rays

(1) Infrared Rays are subdivided into several scheme. ISO 20473 specifies the following scheme: Designation Abbreviation Wavelength Near-Infrared NIR 0.78–3 µm Mid-Infrared MIR 3–50 µm Far-Infrared FIR 50–1000 µm (2) Difference in frequency = The difference between the heating capacity By “Wien’s displacement ...

2. About infrared rays

Although it is not visible, because the light with the power which warms a thing existed “outside red”, it was named “infrared rays.” Infrared rays are the same “Electromagnetic waves” as “X-rays”, “Ultraviolet rays”, “Visible light”, “Microwave”, “Radiofrequency wave”, etc. ...
