keskiinfrapunasäteilyä

Keskiinfrapunasäteilyä, often abbreviated as MIR (Mid-Infrared), refers to a specific portion of the electromagnetic spectrum. This range typically spans wavelengths from approximately 3 micrometers (µm) to 25 micrometers (µm). It falls between the near-infrared (NIR) and the far-infrared (FIR) regions of the spectrum. The energy levels associated with MIR radiation are lower than those of visible light but higher than those of FIR radiation.

MIR radiation is primarily emitted by objects at ambient temperatures, such as the human body, everyday objects, and many biological and chemical compounds. This characteristic makes it particularly useful in various scientific and technological applications. For instance, it plays a crucial role in spectroscopy, where the absorption or emission of MIR light by molecules provides information about their chemical structure and composition. This technique is widely employed in fields like chemistry, environmental monitoring, and medical diagnostics.

Thermal imaging cameras that detect heat signatures often operate in the MIR range. MIR radiation is also used in remote sensing to identify different materials on the Earth's surface and in astronomy to study celestial objects that emit heat. Its ability to penetrate certain materials that are opaque to visible light also contributes to its diverse applications.
