Why measure the refractive index?

The refractive index of a pure material is a physical property and can be used to identify and characterize materials. The refractive index measurement is easy, fast, non-destructive and independent of viscosity. The refractive index of a dissolved substance in a solvent correlates with its concentration. Even quality control of multicompound mixtures of a given mixing ratio can be undertaken by means of a refractive index measurement. Therefore a wide range of scales as well as a wide range of QC applications can be derived from this measuring technology.
