Abbe bench refractometer

This instrument measures the refractive index and mean dispersion values of transparent and translucent liquids or solids.
Refractive indices and mean dispersions are important optical constants of a substance and can be used to determine the optical performance, purity, concentration and dispersion etc. Therefore, the refractometer is an indispensable tool within a wide range of industries, such as petrological, pharmaceutical, chemical and sugar making industries, as well as in factories, colleges and in research institutes.
