Research and quality control laboratories benefit from NIRS alike. While researchers can accelerate their experimentation, QC departments benefit from the ability to analyze hundreds of samples per day – both saving substantial amounts of time and money.
The heart of the interferometer consists of two bi-refringing crystal wedges. By moving one wedge, a part of the light undergoes a phase shift. This phase shift alters the polarization of the entire beam. After passing a polarization filter the interferogram is detected. All wavelengths are measured simultaneously.
