Web20. sep 2013 · Refractometersmeasure the degree to which the light changes direction, called the angle of refraction. A refractometer takes the refraction angles and correlates them to refractive index (nD) values that have been established. Using these values, you can determine the concentrations of solutions. WebRefractometry is a quantitative, non-destructive measuring technique based on optical principles that are evident in nature: For example, when light passes through water, the light beam is reflected – and objects under water appear to have different proportions than those observed above water. This phenomenon is called reflection and refraction.
