Dispersion formula

$$n^2=2.9673173-1.3989565\text{×}10^{-2}λ^{2}+3.3456680\text{×}10^{-2}λ^{-2}+3.0717804\text{×}10^{-3}λ^{-4}-2.6682435\text{×}10^{-4}λ^{-6}+2.8950241\text{×}10^{-5}λ^{-8}$$

Comments

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