LÄHIinfrapunan

LÄHIinfrapunan, often abbreviated as NIR, refers to the near-infrared portion of the electromagnetic spectrum. This region lies between visible light and the mid-infrared, typically spanning wavelengths from approximately 700 nanometers to 2500 nanometers. While invisible to the human eye, NIR radiation possesses properties that make it useful in a variety of scientific and industrial applications.

The interaction of NIR light with matter is primarily based on vibrational and rotational molecular energy levels. Different chemical bonds absorb and reflect NIR light at specific wavelengths, creating unique spectral fingerprints. This characteristic allows for non-destructive analysis and identification of substances without requiring sample preparation or chemical reactions.

Common applications of LÄHIinfrapunan include spectroscopy for quality control in industries such as food, pharmaceuticals, and agriculture. It is used to determine moisture content, analyze chemical composition, and detect impurities. In remote sensing, NIR is crucial for assessing vegetation health, mapping land cover, and studying atmospheric composition. Furthermore, NIR imaging is employed in medical diagnostics and security screening. The relatively low energy of NIR photons also makes it suitable for certain types of lighting and heating applications.
