Dispersion formula

$$n^2=2.8789799-8.7292370\text{×}10^{-3}λ^{2}+2.4425656\text{×}10^{-2}λ^{-2}+4.5491773\text{×}10^{-5}λ^{-4}+4.2802928\text{×}10^{-5}λ^{-6}-7.2834306\text{×}10^{-7}λ^{-8}$$

Comments

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