Dispersion formula

$$n^2=2.8081523-1.4167885\text{×}10^{-2}λ^{2}+1.7693707\text{×}10^{-2}λ^{-2}+7.6788759\text{×}10^{-4}λ^{-4}-7.4886174\text{×}10^{-5}λ^{-6}+4.7044756\text{×}10^{-6}λ^{-8}$$

Comments

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