Dispersion formula

$$n^2=2.5811516-1.1534491\text{×}10^{-2}λ^{2}+1.2703918\text{×}10^{-2}λ^{-2}+5.8195394\text{×}10^{-4}λ^{-4}-4.4244275\text{×}10^{-5}λ^{-6}+2.1000343\text{×}10^{-6}λ^{-8}$$

Comments

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