Dispersion formula

$$n^2=3.1729223-1.4248534\text{×}10^{-2}λ^{2}+2.9168114\text{×}10^{-2}λ^{-2}+1.3428760\text{×}10^{-3}λ^{-4}-9.6178753\text{×}10^{-5}λ^{-6}+8.4042556\text{×}10^{-6}λ^{-8}$$

Comments

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