WebTools. Refractive index contrast, in an optical waveguide, such as an optical fiber, is a measure of the relative difference in refractive index of the core and cladding. The … WebMay 6, 2016 · For wavelengths in the infrared range, refractive indices can be considerably higher compared to the visible range. Germanium is transparent in the wavelength region from 700 to 5000 cm -1 (2-14 μm) and has a refractive index of about 4, making it an important material for infrared optics. 1
The refractive index is an important property of the components of any optical instrument. It determines the focusing power of lenses, the dispersive power of prisms, the reflectivity of lens coatings, and the light-guiding nature of optical fiber. Since the refractive index is a fundamental physical property of a … See more In optics, the refractive index (or refraction index) of an optical medium is a dimensionless number that gives the indication of the light bending ability of that medium. The refractive index … See more The relative refractive index of an optical medium 2 with respect to another reference medium 1 (n21) is given by the ratio of speed of light in medium 1 to that in medium 2. This … See more Refractive index also varies with wavelength of the light as given by Cauchy's equation: The most general form of Cauchy's equation is Usually, it is sufficient to use a two-term form of the equation: See more The refractive index of materials varies with the wavelength (and frequency) of light. This is called dispersion and causes prisms See more Thomas Young was presumably the person who first used, and invented, the name "index of refraction", in 1807. At the same time he changed this value of refractive power into a single number, instead of the traditional ratio of two numbers. The ratio … See more At the atomic scale, an electromagnetic wave's phase velocity is slowed in a material because the electric field creates a disturbance in the charges of each atom (primarily the electrons) proportional to the electric susceptibility of the medium. (Similarly, the See more When light passes through a medium, some part of it will always be absorbed. This can be conveniently taken into account by defining a complex refractive index, See more WebThe refractive index increases in the sensing membrane are significant, ...
