Dispersion formula

$$n^2=3.153652-1.5630638\text{×}10^{-2}λ^{2}+2.8741717\text{×}10^{-2}λ^{-2}+8.0868084\text{×}10^{-4}λ^{-4}-1.0164635\text{×}10^{-5}λ^{-6}+2.9615511\text{×}10^{-6}λ^{-8}$$

Comments

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