Dispersion formula

$$n^2=2.6667537-9.7319259\text{×}10^{-3}λ^{2}+1.7436284\text{×}10^{-2}λ^{-2}+4.7558015\text{×}10^{-4}λ^{-4}-1.7144989\text{×}10^{-5}λ^{-6}+1.1049589\text{×}10^{-6}λ^{-8}$$

Comments

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