The sample is held between the illuminating prism and the refraction prism (RP). Rays that hit the sample/RP interface at an angle large than the critical angle of the interface suffer total internal reflection (TIR) and . The Abbe instrument is the most convenient and widely used refractometer, Fig(1) shows a schematic diagram of its optical system. The sample is contained as a thin layer (~0.1mm) between two prisms. The upper prism is firmly mounted on a bearing that allows its rotation by means of the side arm shown in dotted lines.

A refractometer is a device for measuring the index of refraction of a liquid sample, which is the ratio of light’s velocity in a vacuum to its velocity in the sample. The index of refraction can be measured very precisely; precisions up to ±0.00003 can be obtained, although most commercially-available instruments have a precision of ±0.0001.
A Refractometer works because light travels at different velocities in different mediums, the light beam is bent at the interface between two adjoining materials.This is called “refraction”. There is an angle of light propagation at which refraction no longer occurs, the light beam instead being reflected back into the original material.PDF | On Apr 23, 2018, Ugwu K.C and others published Design, Fabrication and Performance Evaluation of a Portable Hand-Held Refractometer | Find, read and cite all the research you need on .Digital Abbe Refractometer.

The Abbe refractometer is a classic optical instrument used to measure the refractive index of liquids or solids. Abbe refractometers are routinely used in modern chemistry labs for identifying chemical compounds. The instrument is based on the principle of total internal reflection (TIR). In the Abbe' refractometer the liquid sample is sandwiched into a thin layer between an illuminating prism and a refracting prism (Figure 2). The refracting prism is made of a glass with a high refractive index (e.g., 1.75) and the refractometer is designed to be used with samples having a refractive index smaller than that of the refracting prism.

A tool invented in 1869, Abbe refractometers are a highly useful scientific instrument. First developed to measure the refractive nature of liquids, its inventor, Ernst Abbe, wanted to see just how much light bent within various liquids. Using his newly-invented instrument, he started categorizing various liquids into a refractive index. In the 150 years since
