  • De brekingsindex van materialen is afhankelijk van de golflengte; daarom moet ook steeds de beschouwde golflengte vermeld worden. Een gevolg hiervan is de chromatische aberratie van lenzen.De brekingsindex is in mindere mate afhankelijk van onder andere de temperatuur, druk en mechanische spanning. Ook speelt de samenstelling van de stof een rol (bijvoorbeeld door dopering).
  • Many materials have a well-characterized refractive index, but these indices depend strongly upon the frequency of light. Standard refractive index measurements are taken at yellow doublet sodium D line, with a wavelength of 589 nanometers.There are also weaker dependencies on temperature, pressure/stress, et cetera, 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. Thus, it is especially important to cite the source for an index measurement if precision is required.In general, an index of refraction is a complex number with both a real and imaginary part, where the latter indicates the strength of absorption loss at a particular wavelength—thus, the imaginary part is sometimes called the extinction coefficient . Such losses become particularly significant, for example, in metals at short (e.g. visible) wavelengths, and must be included in any description of the refractive index.
