PRINT ATAGO ABBE .Ernst Abbe (1840–1905), working for Carl Zeiss AG in Jena, Germany in the late 19th century, was the first to develop a laboratory refractometer. These first instruments had built-in thermometers and required circulating water to control instrument and fluid temperatures. They also had adjustments for eliminating the effects of dispersion and analog scales from which the .Abbe’s Refractometer The Abbe instrument is the most convenient and widely used refractometer, Fig(1) shows a schematic diagram of its optical system.

Its original design was so successful that even through today it is over 141 years old, it is still used and copied in new devices. Abbé refractometer working principle is based on critical angle. Sample is put between 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.Accessory parts: Abbe refractometer – ORT The following model is a simple yet highly reliable Abbe refractometer with a digital thermometer. Liquid, solid and pasty samples can be evaluated. This refractometer is robust, accurate and easy to use. Optionally a solide aluminium case for transport and storage is available.

El Refractómetro de Abbe se utiliza para medir índices de Refracción (nD) de líquidos que sean transparentes o translúcidos y sólidos siendo el uso más frecuente con líquidos transparentes. El índice de refracción es una importante constante óptica en las sustancias, y pueden ser 2. The beam is so oriented that some of its rays just graze the surface, so that one observes in the transmitted light a sharp boundary between light and dark. Measurement of the angle at which this boundary occurs allows one to com- pute the value of and hence of n. The main part of Abbe’s refractometer (Figure 2) is prism lens.
