Refractometer parts and functions
In drug diagnostics, a refractometer is used to measure the specific gravity of human urine. In gemology, the gemstone refractometer is one of the fundamental pieces of equipment used in a gemological laboratory. Gemstones are transparent minerals and can therefore be examined using optical methods. Zobraziť viac A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The index of refraction is calculated from the observed refraction angle using Snell's law. For mixtures, the … Zobraziť viac There are four main types of refractometers: traditional handheld refractometers, digital handheld refractometers, laboratory or Abbe refractometers (named for the instrument's inventor and based on Ernst Abbe's original design of … Zobraziť viac • Brix • Oechsle scale • Plato scale • Baumé scale Zobraziť viac • Sella, Andrea (November 2008).

Then, the patient is shown an image that moves in and out of focus. As reflections are made, several measurements determine when the eye is properly focused. These final figures determine the level of vision correction needed.
