NIR Spectroscopy
Near-infrared spectroscopy (NIRS) is a spectroscopic method based on the absorption of electromagnetic radiation at wavelengths from 700 to 2500nm. NIRS is a form of molecular spectroscopy. NIR radiation is absorbed by molecules through a mechanism involving molecular vibration. Not all bonds in a molecule are capable of absorbing infrared radiation. Only those bonds that have a dipole moment that changes as a function of time are capable of absorbing infrared radiation. For example, O–H, N–H, C–H, S–H bonds are strong NIR absorbers. The most prominent absorption bands occurring in the NIR region are related to overtones and combinations of fundamental vibration. In vibrational spectroscopy, an overtone band is the spectral band that occurs in a vibrational spectrum of a molecule when the molecule makes a transition from the ground state (v=0) to the second excited state (v=2), which is called the first overtone, or from the ground state (v=0) to the third excited state (v=3), which is called the second overtone. NIRS has unique properties which makes it very useful for the analysis of most solid, slurry and liquid samples. NIRS in conjunction with chemometrics has revolutionized much of the general area of analyses.
NIR Measurement
Karl Norris, the Father of Near-Infrared Spectroscopy, discovered that the NIR region had a convenient combination of useful properties that caused it to be uniquely suited to being used for various applications to chemical analysis. The advantages of the use of NIR are speed, cost, range of applicability, non-destructive, environmental benefits due to non-use of chemicals, and simultaneously multi-component analysis. NIR analysis can be used successfully when sample is not in a clear solution (e.g. a powdered solid, an emulsion, a suspension, etc.). Spectral measurement can be taken using diffuse reflection rather than transmission. NIR analysis has been rapidly and widely applied in agriculture, petroleum, pharmaceuticals, biometrics, soil analysis, and so on. The advent of NIR analysis in conjunction with chemometrics has revolutionized much of the general area of analyses. There are four standard measurement modes for the acquisition of NIR spectra from a sample: transmission, reflectance, transflectance, and interaction.
ISC NIRScan Solution
InnoSpectra Corporation (ISC) is devoted to the development of NIR analysis solution. ISC is committed to providing a series of compact and cost-effective DLP-based NIR spectrometers including fiber input modules, diffuse reflective modules and transmissive modules in different wavelength range from 900nm to 2400nm to support all sorts of applications. The optical engine of the DLP-based NIR spectrometer adopts a post-dispersive architecture, which is composed of an entrance slit, a set of collimating lenses, a bandpass filter, a diffraction grating, a set of focusing lenses, a DMD (digital micromirror device), a set of light receiving lenses and a single-element InGaAs detector. A DLP-based spectrometer uses a DMD and a single-element InGaAs detector to replace a traditional linear array detector. Compared to the spectrometer with a linear array detector, NIRScan is equivalent to a 128-pixel device at the same wavelength range and spectral resolution.
DLP technology in NIR spectroscopy provides the following advantages:
- 1.Higher performance through the use of a larger single-element detector (ϕ=1mm) in comparison to a linear array with very small pixels (e.g. 50μm).
- 2.The high resolution DMD (854*480 pixels) allows custom patterns to optimize the optical performance of each individual system.
- 3.With programmable patterns, a DLP spectrometer can use Hadamard patterns to improve SNR. In Hadamard mode, a wide DMD pattern is displayed, so higher optical energy will be captured by the InGaAs detector.
