This problem is encountered in the automobile industry, where polypropylene master plaques are commonly used as the standards constructed from different materials than the sample being evaluated. The paper demonstrates how these problems result from the impact of a polymer's refractive index on the ...
refractive index of the material for some intermediate colour such as the sodium “D” Fraunhofer line of wavelength 5893 angstroms. Thedispersive power (w) of the material is then defined as the ratio of the difference between the “F” and “C” indices and the “D” index reduced by 1...

The index of refraction is a measure of the speed of light in matter. The dispersion, or change of the refractive index with wavelength, can be represented mathematically many different ways for use in optical design. What is covered in this paper is not what the index of refraction is, bu...
It specifies, for example, how fast light travels in a material or how much light is reflected at an interface. Refractive index is a useful constant as it is directly related to measurable quantities such as reflectance and absorption. At a more fundamental level, how- ever, a material׳...
Data were taken for 28 different thin-film materials, and representative refractive index dispersion curves are shown for some of them. The dispersion constants for each material evaluated are also presented. 展开 DOI: 10.1147/rd.173.0256 被引量: 23 ...

Therefractive index,n,of a material is the ratio of the velocity of light infree spaceto that in the material in question. Therefractive indexof glass is around 1.5. This means that light travels in glass at around 300000/1.5 = 200000km/s. It is a little publicised fact that the spee...
First, light rays change direction when they cross the interface from air to the material, an effect that is used in lenses. Second, light reflects partially from surfaces that have a refractive index different from that of their surroundings. ginge The refractive index, n, of a medium is ...
Notably, the fabricated optical transmission waveguides using the resultant HRIP with the highest refractive index display a reduced propagation loss compared with that generated by the commercial material of SU-8. In addition, the tetraphenylethylene containing polymer not only exhibits a reduced ...
