Near-infrared (NIR) research involves the study and application of electromagnetic radiation with wavelengths ranging from 700 to 2500 nanometers. NIR light is invisible to the human eye but can penetrate deeper into materials than visible light, making it useful for various scientific and technological purposes. Researchers in the field of NIR spectroscopy use this technology for non-destructive analysis of materials, such as determining the composition of agricultural products, pharmaceuticals, and polymers. NIR imaging techniques are also commonly used in medical diagnostics, environmental monitoring, and industrial process control. Overall, NIR research plays a crucial role in advancing our understanding of materials and their properties, as well as developing innovative technologies in a wide range of fields.
