List of indices of refraction | Revolvy

List of indices of refraction 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
