Liquid refractometry by the rainbow method
Applied Optics, 1998A new method for measuring the refractive index of liquid, proposed in a previous paper [Appl. Opt. 36, 5552-5556 (1997)], has been developed. The minimum deviation of a laser beam deflected by a liquid-filled cylindrical cell was calculated by use of geometric optics.

Abstract The refractive index of materials is one of their most basic optical properties. In the case of liquids, the refractive index has been employed by chemists for many years to document sample purity. The simplest way to determine the refractive index is by measuring the angle at which light bends at an interface between two ...

Refractometry and Interferometry of Living Cells*†
Journal of the Optical Society of America, 1957The development of phase contrast and interference microscopy has focused attention on the possibility of measuring the refractive indexes of living cells. Difficulties are encountered in applying immersion methods of refractometry to living cells because the choice of immersion media is very limited.

Three-dimensional rainbow refractometry
Optics LettersWe propose a new, to the best of our knowledge, rainbow technique called three-dimensional rainbow refractometry (TDRR), with a cylindrical lens in the signal collecting system. With a TDRR model based on the ray transfer matrix developed, it is proved that the tilt angle of the rainbow signal is related to the axial position of the droplet, which ...

Refractometry of fluids in microscopic tubes
Applied Optics, 1979Fluid filling a tube immersed in a medium that matches the index of the tube acts as a cylindrical lens. Because of geometrical aberrations, the focal length cannot be used directly for an accurate determination of refractive index. By observing the focal position with a microscope that has an aperture regulating diaphragm in the back focal plane, the ...
