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 radiation is important in various applications, including thermal imaging, spectroscopy, and communication technologies. In nature, mid-infrared light is emitted by warm objects, such as the Sun and living organisms. It is also used in scientific research to study molecular vibrations, which helps identify different substances. Additionally, mid-infrared sensors are utilized in environmental monitoring and medical diagnostics for detecting specific gases and analyzing biological samples.
