Laboratory refractometers are optical devices designed to measure the refractive index of substances. The refractive index indicates how light propagates through a medium, providing valuable insights into the composition and characteristics of the material being analyzed. These instruments are widely utilized across industries for their accuracy, reliability, and efficiency in determining concentrations, purity levels, and quality attributes of liquids and semi-solid substances.
At the heart of laboratory refractometers lies the principle of refraction, where light bends as it passes from one medium to another with a different optical density. By measuring the angle of refraction, refractometers can calculate the refractive index of a sample, offering quantitative data for analysis and interpretation.
