  2. Refractometer - Wikipedia

    en.wikipedia.org/wiki/Refractometer

    The refractometer is used to help identify gem materials by measuring their refractive index, one of the principal properties used in determining the type of a gemstone. Due to the dependence of the refractive index on the wavelength of the light used (i.e. dispersion), the measurement is normally taken at the wavelength of the sodium line D ...

  3. Cutting fluid - Wikipedia

    en.wikipedia.org/wiki/Cutting_fluid

    Cutting fluid is a type of coolant and lubricant designed specifically for metalworking processes, such as machining and stamping. There are various kinds of cutting fluids, which include oils, oil-water emulsions, pastes, gels, aerosols (mists), and air or other gases. Cutting fluids are made from petroleum distillates, animal fats, plant oils ...

    en.wikipedia.org/wiki/Abbe_refractometer

    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 ...

    en.wikipedia.org/wiki/Refractive_index

    In optics, the refractive index (or refraction index) of an optical medium is a dimensionless number that gives the indication of the light bending ability of that medium. Refraction of a light ray. The refractive index determines how much the path of light is bent, or refracted, when entering a material. This is described by Snell's law of ...

  6. Inline process refractometer - Wikipedia

    en.wikipedia.org/wiki/Inline_process_refractometer

    Inline process refractometers are a type of refractometer designed for the continuous measurement of a fluid flowing through a pipe or inside a tank. First patented by Carl A. Vossberg Jr. US2807976A - Refractometer US2549402A, these refractometers typically consist of a sensor , placed inline with the fluid flow, coupled to a control box.

  7. Digital handheld refractometer - Wikipedia

    en.wikipedia.org/wiki/Digital_handheld_refractometer

    Digital handheld refractometers are generally more precise than traditional handheld refractometers, but less precise than most benchtop refractometers. They also may require a slightly larger amount of sample to read from since the sample is not spread thinly against the prism. The result may be displayed in one of various units of ...
