Dispersion formula

$$n^2=2.6165865-1.1427854\text{×}10^{-2}λ^{2}+2.2534361\text{×}10^{-2}λ^{-2}+1.5512890\text{×}10^{-3}λ^{-4}-1.1769852\text{×}10^{-4}λ^{-6}+1.2401891\text{×}10^{-5}λ^{-8}$$

Comments

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