IRenergie
IRenergie, or infrared energy, denotes the portion of the electromagnetic spectrum with wavelengths longer than visible light and shorter than microwaves. In physics and engineering, infrared radiation is often associated with heat and thermal emission from objects at ordinary temperatures. The infrared range is typically divided into near infrared (about 0.75 to 1.4 μm), mid infrared (1.4 to 8 μm), and far infrared (8 to 1000 μm).
The physical basis of IRenergie lies in thermal motion and quantum transitions. According to Planck's law, every
Generation and detection are central to IRenergie applications. Common sources include the Sun, hot surfaces, electric
Interaction with matter varies across the IR range. Some materials are transparent to near-IR but opaque in
Safety considerations note that IRenergie is non-ionizing but can cause thermal injury to skin and eyes with
