Unlocking the Secrets of the Near Infrared Spectrum: A New Era in Scientific Exploration

Near infrared (NIR) technology has emerged as a crucial tool in various industries, offering a non-destructive and non-intrusive method for analyzing materials. This technology utilizes the near infrared region of the electromagnetic spectrum, which spans from 780 to 2500 nanometers, to detect and measure the chemical composition of substances. This article aims to provide an in-depth introduction to the near infrared industry, covering its applications, benefits, challenges, and future prospects.

Introduction to Near Infrared Technology

Near infrared technology operates on the principle that different chemical bonds absorb specific wavelengths of light. When near infrared light passes through a material, the bonds within the material absorb some of the light energy, causing the molecules to vibrate and rotate. The resulting changes in the molecular structure can be detected and analyzed to determine the composition of the material.
