Dispersion formula

$$n^2=2.4325095-8.2983201\text{×}10^{-3}λ^{2}+1.4609976\text{×}10^{-2}λ^{-2}+1.5397291\text{×}10^{-7}λ^{-4}+3.7275782\text{×}10^{-5}λ^{-6}-1.7621673\text{×}10^{-6}λ^{-8}$$

Comments

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