A refractometer is a simple instrument used for measuring concentrations of aqueous solutions such as gases, liquids, and translucent solids. Different types of refractometers are available depending on the application. Refractometers can be handheld, compact, benchtop, Abbe, and Brix as well as different .Abbe designed an instrument for measuring the dispersion of light and this became the precursor for the so-called ‘Abbe Refractometer’. Bellingham + Stanley offer a number of Abbe refractometers and a choice can be made in accordance with the measurement requirement and budget availability.
The explosive growth of laboratory work after WW 1 led a number of other companies to begin its manufacture as well, including Adam Hilgar and Stanley in Great Britain, and Spencer Lens Co., Bausch & Lomb, Gaertner, and Valentine in the U. S. Ernst Abbe constructed the first “Abbe” 3 refractometer in 1869. Five years later, in 1874, he .The Palm Abbe digital refractometer is equipped with from one to five scales depending on the model. A scale represents a specific unit of measure for a specific fluid. For instance, a unit of measure could be percent by volume, percent by weight, specific gravity, density, molar concentration, freeze point, boil point, etc. .The AR4 is a classic Abbe refractometer. The scales can be set manually using the drive knob and the refractive index and Brix values are read off using an eyepiece. The temperature is measured with the integrated digital thermometer and displayed on the LCD. The AR4 refractometer can be connected to a circulation thermostat for temperature .

Likewise, the reflectivity of a well-collimated beam (e.g. a laser beam) near the critical angle in an .
The Abbe refractometer derives its name from the 19th Century physicist and father of modern optical technology, Ernst Abbe (1840- 1905). He was the co-founder of the Carl Zeiss Jena Optical Company and Schott Glasswerk. Abbe designed an instrument for measuring dispersion which became the precursor for a refractometer – the Abbe Refractometer.
Brief history of refractometers. Ernst Abbé designed his refractometer in 1869, but it didn't became commercially available from Carl Zeiss before 1881. .

Snell's Law • Describe the relationship between the angles of incidence and refraction, • Snell's law is used to determine the direction of light rays through refractive media with varying indices of refraction. The indices of refraction of the media, labelled n1, n2 and so on, are used to represent the factor by which a light ray's speed decreases when travelling .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
Hand-held refractometer. A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry).The index of refraction is calculated from the observed refraction angle using Snell's law.For mixtures, the index of refraction then allows the concentration to be determined using mixing rules such as the Gladstone–Dale relation and .The modern Abbe refractometer invented at the Carl Zeiss Works was exclusively manufactured by Zeiss until the early 20th century.
