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. Ver mais Many materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion. Standard refractive index measurements are taken at the "yellow doublet" Ver mais • Sellmeier equation • Corrective lens#Ophthalmic material property tables • Optical properties of water and ice Ver mais • International Association for the Properties of Water and Steam • Ioffe institute, Russian Federation • Crystran, United Kingdom Ver mais WebTheoretically, there is no limit to the refractive index.
