An Abbe refractometer is a scientific instrument used to measure the refractive index of liquids and solids. Named after the German physicist Ernst Abbe, this device operates on the principle of...
immersion refractometer
A type of refractometer designed to measure the refractive indices of liquids. A section of the instrument is immersed into the sample being measured.
Jamin refractometer
An instrument designed to measure the index of refraction of a gas by the interference patterns formed by two beams, one of which passes through a vacuum tube in which the gas is slowly released.
Williams refractometer
A refractometer that has a greater resolving power than a standard refractometer, and that uses a pentagonal prism to split the light from a single slit into two beams.
