INDEX OF REFRACTION BY INTERFERENCE METHODS

WebRayleigh interferometer. An optical interferometer in which two rays of light, emanating from a single slit, are collimated by a lens, pass through separate slits and cells, and are brought to focus by a second lens so that interference fringes become visible. Also known as Rayleigh refractometer. Want to thank TFD for its existence? WebThe rayleigh refractometer works by having light pass through a vertical slit, and then collimated through a lens which passes it through two vertical slits to line it up parallel with two test tubes that the index of refractions will be compared. Typically one of the tubes will be filled with something such as air so that it has a known index.

The index of refraction is calculated from Snell's law while for mixtures, the index of refraction can be calculated from the composition of the material using several mixing rules such as the Gladstone–Dale relation and Lorentz–Lorenz equation.

WebNov 20, 2024 · A refractometer is commonly used to test the brix level (sugar content) in ripening vegetables and fruits, or to indicate whether some elements or nutrients are missing from the plants. Most plants with a low brix reading indicate that not enough nutrients are being absorbed by the roots. On the other hand, an excessively high reading can also ... WebFeb 1, 2009 · In the Rayleigh refractometer, a series of prisms split the light source through sampling and control tubes. The refractometer is calibrated for a particular gas and, by means of aligning the fringe patterns created by each sample, a scale can be made to give the concentration of that gas.
