  • Immersion refractometer
    Patent number: 10145789
    Abstract: A device for measuring the absolute value of the refractive index of a liquid by immersion uses the optical properties of a cylindrical waveguide with a solid core and normal angle of incidence of the light source. The device consists of a transparent tube forming the enclosure of the waveguide, impervious to the surrounding liquid and partially filled with a transparent solid or liquid material of appropriate index of refraction, a fiber optic means of inputting light via a LED or laser and fiber optic means of coupling emerging light to a photodetector. The emerging light intensity is a function of the index of refraction of the surrounding liquid.
