Dispersion formula

$$n^2=2.2668912-9.3866212\text{×}10^{-3}λ^{2}+1.2174195\text{×}10^{-2}λ^{-2}+5.076903\text{×}10^{-4}λ^{-4}-3.3573414\text{×}10^{-5}λ^{-6}+2.9059013\text{×}10^{-6}λ^{-8}$$

Comments

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