logX   logY   eV

Dispersion formula

$$n^2=2.9679939-1.3679779\text{×}10^{-2}λ^{2}+3.0300794\text{×}10^{-2}λ^{-2}+1.2266553\text{×}10^{-3}λ^{-4}-4.4824019\text{×}10^{-5}λ^{-6}+7.2105225\text{×}10^{-6}λ^{-8}$$

Comments

Refractive index is relative to air at standard conditions; Wavelength in dispersion formula is as measured in air and expressed in micrometers
