- The basis of operation of the visual or manual refractometer:
Eye refractometer or manual refractometer is an analog instrument which is used based on measuring the refractive index of liquids and according to the main critical angle by internal lenses and prisms, a shadow is created on the graduated part of the eye refractometer and it is observed through the eye lens and the sample It is placed between the covering part on the refractometer and the prism, and the transmitted light after passing through the sample and the prism creates a shadow in the form of two dark and light areas, and the resulting line between these two parts represents the number of the value measured by the refractometer.
