Mid-infrared refers to a specific range of wavelengths in the electromagnetic spectrum, typically from about 3 to 8 micrometers. This range is situated between the near-infrared and far-infrared regions. Mid-infrared light is often used in various applications, including thermal imaging, spectroscopy, and communication technologies. One of the key features of mid-infrared light is its ability to interact with molecular vibrations, making it useful for identifying chemical compounds. Instruments like FTIR spectrometers utilize mid-infrared light to analyze materials, helping scientists and researchers understand the composition of substances in fields such as chemistry and environmental science.
