NIR

NIR is a highly flexible form of analysis, which can be applied to a broad range of research and industrial process applications. Long a staple technology in remote sensing, NIR reflectance spectroscopy has become popular within industrial markets as a cost-effective tool for measuring materials to optimize processes and manage costs. Capable of examining irregular surfaces with the same ease as a carefully prepared sample, NIR is non-destructive, and requires little or no sample preparation. It can also be used to analyze multiple constituents in a single scan. Combined with a calibration model, NIR analysis is a powerful tool for a multitude of applications. ASD spectrometer and spectroradiometer systems convert measured data into actionable information to help optimize processes or improve research. NIR reflectance spectroscopy is a method that makes use of the near infrared region of the electromagnetic spectrum (from about 700 to 2500 nanometers). Intermolecular hydrogen bondings and dipol interactions alter vibrational energy and thus lead to shifts in existing absorption bands or even the formation of new absorption bands. The fact that the spectra are strongly impacted by physical parameters (e.g., particle size, density, and moisture content) is the reason why NIRS is ideally suited for the capture of these characteristics. By measuring light scattered off of and through a sample, NIR reflectance spectra can be used to quickly determine a material’s properties without altering the sample. ASD has taken NIR technology a step further with the Goetz spectrometer, a hybrid system that uses a combination of visible and NIR regions (Vis/NIR) to include wavelengths from 350 nm to 2500 nm. The instruments have three separate spectrographs optimized for specific wavelength regions. This design features excellent stray light performance, high photometric sensitivity, and a rapid scan time not attainable by most traditional NIR instruments.
