Dispersion formula

$$n^2=2.9564361-1.9762195\text{×}10^{-2}λ^{2}+2.9878823\text{×}10^{-2}λ^{-2}+5.1830852\text{×}10^{-3}λ^{-4}-5.4202389\text{×}10^{-4}λ^{-6}+4.8463245\text{×}10^{-5}λ^{-8}$$

Comments

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