A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The index of refraction is calculated from Snell's law while for mixtures, the index of refraction can be calculated from the composition of the material using several mixing rules such as the Gladstone–Dale relation and Lorentz

In the Abbe' refractometer the liquid sample is sandwiched into a thin layer between an illuminating prism and a refracting prism. 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

The telescope consists of an objective (5) and eyepiece (9), as well as a plate (8) with a dotted alignment line. This plate is placed in the joint focal plane of lenses (5) and (9).
In the Abbe' refractometer the liquid sample is sandwiched into a thin layer between an illuminating prism and a refracting prism. 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.

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. This is called the critical angle. Critical angle is the result of light interfacing at two mediums.
Abbe’s refractometer, temperature controller, light source and samples. Abbe’s Refractometer . 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.
A refractometer measures the "bending" of light as it passes through some material. This phenomenon is known as refraction, and its measurement is called a refractive index. The refractive index for a solution of a known substance can be used to calculate the concentration of that solution. For example,
Refraction in the prism combining various light sources. As you see, there is plenty of rays refracted and exiting the prism, but they all are on one side of the ray that is defined by the critical angle. There are no rays entering the prism from below, that can get refracted and leave the prism in the direction shown by dotted gray line.
High accuracy over a wide measuring range. Abbemat refractometers determine the refractive index with an accuracy of up to ± 0.00002 nD, within a measuring range of 1.26 nD to 1.72 nD and a temperature range from 4 °C to 125 °C.
Keep in mind that most of us see just as well with a low ABBE VALUE lens as compared to a high ABBE VALUE lens. Crown glass is most commonly used for eyeglass lenses with an index of refraction of 1.523. There are however, 50 glass formulations used today for various optical applications, all with its unique properties.
Refractometry » Refraction In general, light travels in straight lines, but there are some specific circumstances in which light path can become more complicated. First of all, light can get reflected from a mirror while path before and after reflection is straight, during reflection light changes its direction.
Refractometer is an optical device that can be used to measure the refractive index of a substance (usually fluid) and, by converting the refractive index, one
where r specific refraction, d density, n refractive index. As refractive index depends on the wavelength, refractive index tables usually contain information about the wavelength used for measurement. In most cases values of refractive index are listed for yellow sodium light with wavelength of 589.3 nanometers. This site is in construction.

refraction was mathematically formulated first by Ibn Sahl in 984. His discovery was not known in The first laboratory instrument to accurately measure the refractive index of liquids was developed by Ernst Abbe in 1874. Speed of light Refractive index measurement is actually a measurement of the speed of light in a medium. The
