What is refractometry
A total internal reflection of the light takes place. The refractive index is then determined using the critical angle, at which total internal reflection begins. The refractive index nD is the value for the ratio of the speed of light in vacuum (C Vacuum) to the speed of light in a medium (C Medium ). D in nD refers to the wavelength of the ...

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.

Hand Held, Digital, Bench and Abbe Refractometers
Refractometers. Refractometers are optical instruments used to measure the refractive index of liquids, gases, and translucent solids. Refractive index, also called index of refraction, is the angle that a ray of light bends when passing from one medium into another. The refractive index can provide information for us about the behaviour of light.

Abbe-Number | Edmund Optics
Also known as Abbe constant, it inversely quantifies the amount of dispersion in an optical medium. It is given by a function of the refractive index of a material at the f (486.1nm), d (587.6nm), and c (656.3nm) wavelengths. A material with a high Abbe number means that the different wavelengths will have nearly the same index of refraction in ...
