Glossary
  • refractometer An instrument used to measure the refractive index of solids and liquids. Several types exist, the most common being the Abbe refractometer.
  • Abbe refractometer Device which measures the index of refraction of glass as well as the dispersion over visible range.
  • index of refraction The ratio of the velocity of light in a vacuum to the velocity of light in a refractive material for a given wavelength.
  • 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.
  • 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.
