  2. Refractometry - Wikipedia

    en.wikipedia.org/wiki/Refractometry

    Refractometry is the analytical method of measuring substances' refractive index (one of their fundamental physical properties) in order to, for instance, assess their composition or purity. A refractometer is the instrument used to measure refractive index ("RI").

    en.wikipedia.org/wiki/Refractometer

    Refractometry [ edit ] Standard refractometers measure the extent of light refraction (as part of a refractive index) of transparent substances in either a liquid this is then used in order to identify a liquid sample, analyze the sample's purity, and determine the amount or concentration of dissolved substances within the sample.

    North Dakota 20 in Devils Lake, August 2013. Starting at US 52 in downtown Jamestown, ND 20 follows 4th Street NE until 5th Avenue NE, then curves onto 13th Street NE until 12th Avenue NE where ND 20 follows 12th Avenue out of Jamestown. 21.3 miles away from the intersection, ND 20 turns right onto ND 9 and continues for about six miles before turning off in Courtenay and running for 16.8 ...

    In the simplest form, uniaxial birefringence, there is only one special direction in the material. This axis is known as the optical axis of the material. [ 1 ] : 230 Light with linear polarization perpendicular to this axis will experience an ordinary refractive index n o while light polarized in parallel will experience an extraordinary ...

    Among these are methods for determination of dry solids content by polarimetry, densimetry and refractometry, color (extinction coefficient at 420 nm), reducing sugars, and the presence of metals such as arsenic and copper.

  9. Cauchy's equation - Wikipedia

    en.wikipedia.org/wiki/Cauchy's_equation

    The most general form of Cauchy's equation is n ( λ ) = A + B λ 2 + C λ 4 + ⋯ , {\displaystyle n(\lambda )=A+{\frac {B}{\lambda ^{2}}}+{\frac {C}{\lambda ^{4}}}+\cdots ,} where n is the refractive index, λ is the wavelength, A , B , C , etc., are coefficients that can be determined for a material by fitting the equation to measured ...
