Keskiinfrapuna

Keskiinfrapuna refers to a specific band within the infrared electromagnetic spectrum. This region typically spans wavelengths from approximately 3 to 25 micrometers. Unlike near-infrared radiation, which is closer to visible light and often associated with heat emitted by warm objects, or far-infrared radiation, which is longer in wavelength and associated with cooler objects and cosmic background radiation, the mid-infrared band has distinct characteristics and applications.

Objects at room temperature and above emit a significant amount of radiation in the mid-infrared spectrum. This makes it particularly useful for thermal imaging and remote sensing of temperatures. For instance, thermal cameras used in security, industrial inspection, and medical diagnostics often operate in this range. Many organic molecules also have unique absorption and emission signatures in the mid-infrared, allowing for their identification and analysis through spectroscopy. This property is exploited in fields such as chemistry, environmental monitoring, and astrophysics for studying the composition of planets, stars, and interstellar gas. The atmospheric transmission window in the mid-infrared allows astronomers to observe celestial objects and their chemical makeup from Earth-based telescopes.
