## Refractometer Wikipedia

A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry).The index of refraction is calculated from Snell's law while for mixtures, the index of refraction can be calculated from the composition of the material using several mixing rules such as the GladstoneDale relation and LorentzLorenz equation
