WebFor common optical glasses, the refractive index calculated with the three-term Sellmeier equation deviates from the actual refractive index by less than 5×10 −6 over the wavelengths' range [4] of 365 nm to 2.3 μm, which is of the order of the homogeneity of a glass sample. [5] Web1. máj 2014 · The measured refractive index is found to diverge from a truncated Kramers–Kronig calculation. The divergence can be explained by assuming that the polymer host is damaged as well as the dye. These results support the hypothesis that the irreversibly decayed species is related to polymer damage.
