Refractive indices indices

Many materials have a well-characterized refractive index, but these indexes depend strongly upon the frequency of light. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength of 589 nanometers. There are also weaker dependencies on temperature, pressure/stress, etc., as well on precise material compositions (presence of dopants, etc.); for Many materials have a well-characterized refractive index, but these indexes depend strongly upon the frequency of light.

Refractive Index of Polymers The refractive index ( n ) is an important optical property of polymers and is widely used in material science. The knowledge of the refractive index is crucial in all optical applications of transparent polymers. Refractive Index (Index of Refraction) Refractive Index (Index of Refraction) is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density. The refractive index variable is most commonly symbolized by the letter n or n' in descriptive text and mathematical equations. Refractive index is the measurement of that angle: the ratio of the velocity of light in the air to the velocity of light in a medium through which it passes. Knowing a refractive index can help you (a) identify the medium in a liquid or (b) measure the purity and concentration of a medium in that liquid. The index of refraction, or refractive index, is a measure of how fast light rays travel through a given medium. Alternatively, it could be said that refractive index is the measure of the bending of a light ray when passing from one medium to another. The refractive index is a function of the wavelength.The most common characteristic quantity for characterization of an optical glass is the refractive index n in the middle range of the visible spectrum. This principal refractive index is usually denoted as n d – the refractive index at the wavelength 587.56 nm or in many cases as n Refractive indices of water and ice in the 0.65- to 2.5-gm spectral range Linhong Kou, Daniel Labrie, and Petr Chylek New accurate values of the imaginary part, k, of the refractive index of water at T = 22 C, supercooled Ohara Group is an international group of companies with headquarters in Japan and subsidiaries in Japan (Ohara, Inc.), United States (Ohara Corporation), and Germany (Ohara, GmbH). Ohara manufactures optical and electronic products and also offers measurement services, in particular measurement of refractive indices of solids and liquids.

The index of refraction, or refractive index, is a measure of how fast light rays travel through a given medium. Alternatively, it could be said that refractive index is the measure of the bending of a light ray when passing from one medium to another.

The refractive indices of most substances vary considerably with light of different wavelengths. When no wavelength is given, the refractive index is assumed to be  

The refractive indices which were measured along the dashed line in Figure 1(c) at the radius of 0, 25 mm, 50 mm, 65 mm, 75 mm and plotted in Figure 4 demonstrate that the refractive indices of the film are also approximately consistent with the minority carrier lifetime, the same as the situation discussed previously. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength of 589 nanometers. There are also weaker dependencies on temperature , pressure / stress , etc., as well on precise material compositions (presence of dopants , etc.); for many materials and typical conditions, however, these variations are at the percent level or less. Refractive index is the ratio of the velocity of light of a specified wavelength in the air to its velocity in the examined substance. When this principle of measurement is used it may be defined as the sine of the angle of incidence divided by the sine of the angle of refraction.
