Dispersion formula

$$n^2=2.9753491-1.4613470\text{×}10^{-2}λ^{2}+2.1096383\text{×}10^{-2}λ^{-2}+1.1980380\text{×}10^{-3}λ^{-4}-1.1887388\text{×}10^{-4}λ^{-6}+7.3444350\text{×}10^{-6}λ^{-8}$$

Comments

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