The prism has a clear cover that spreads the liquid and allows light to pass through. When a ray of light hits the prism through the illuminator cover, it bends.

Web11 de ago. de 2014 · Last Updated: 2014-08-11. Refractometers are instruments to measure substances dissolved in water and certain oils. The refractometer works using the principle of light refraction through liquids. As light passes from air into a liquid it slows down. This phenomenon is what gives a "bent" look to objects that are partially submerged in water. 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 the 'critical angle') and inline process refractometers. There is also the Rayleigh Refractometer used (typically) for measuring the refractive indices of gases. In laboratory medicine, a refractometer is used to measure the total plasma protein in a blood sa… Web20 de set. de 2013 · A refractometer takes the refraction angles and correlates them to refractive index (nD) values that have been established.
