Dispersion formula

$$n^2=2.9466133-1.4813612\text{×}10^{-2}λ^{2}+2.0753291\text{×}10^{-2}λ^{-2}+7.1087608\text{×}10^{-4}λ^{-4}-4.178079\text{×}10^{-5}λ^{-6}+2.5896668\text{×}10^{-6}λ^{-8}$$

Comments

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