Dispersion formula

$$n^2=2.9584947-1.0230213\text{×}10^{-2}λ^{2}+4.0573993\text{×}10^{-2}λ^{-2}+4.9840238\text{×}10^{-4}λ^{-4}+1.5597439\text{×}10^{-4}λ^{-6}+3.8632431\text{×}10^{-6}λ^{-8}$$

Comments

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