What is the range of the NIR spectrum?

Published in Science 1 min read

The near-infrared (NIR) spectrum ranges from approximately 780 nanometers (nm) to 2500 nm.

This region falls between the visible light spectrum and the mid-infrared (MIR) spectrum.

NIR radiation is invisible to the human eye but can be detected by specialized instruments.

NIR spectroscopy is a powerful technique used in various applications, including:

  • Food analysis: Determining moisture content, fat content, and protein content in food products.

  • Material science: Identifying and characterizing materials based on their chemical composition and structure.

  • Medical diagnostics: Detecting and monitoring diseases by analyzing tissue and blood samples.

  • Remote sensing: Mapping vegetation, soil, and water resources from satellites and aircraft.

    The specific wavelength range used in NIR applications can vary depending on the specific application and the instrument used.
