In modern times this formula isn’t used as frequently, since the development of high-accurate refractometers made it possible to measure R.I. differences at a resolution of 0.00001. However, information regarding R.I. values at other wavelengths is lost. By accurately measuring samples at 7 separate wavelengths, the DSR-λ effectively takes R.I. measurements to the “fingerprinting” level. Many chemically different solutions may exhibit similar R.I. values at the traditional 589.3nm (sodium) wavelength. However, when a spectral-analysis takes place at the R.I. level, the key differences can b...
