Dispersion properties of optical polymers acta physica polonica a 116 585 587 2009 fit of the experimental data with the sellmeier dispersion formula.
Conditions spec sheet n absolute.
Standard refractive index measurements are taken at the yellow doublet sodium d line with a wavelength of 589 nanometers.
Conditions spec sheet n absolute.
Conditions spec sheet n absolute.
Many materials have a well characterized refractive index but these indexes depend strongly upon the frequency of light.
The refracted beam in sheet 2 makes an angle of 31 7 with the normal.
Three sheets of plastic have unknown indices of refraction.
There are also weaker dependencies on temperature pressure stress etc as well on precise material compositions presence of dopants etc.
