Dispersion formula

$$n^2=2.9883142-1.4513238\text{×}10^{-2}λ^{2}+2.2073802\text{×}10^{-2}λ^{-2}+6.2081502\text{×}10^{-4}λ^{-4}-3.7134477\text{×}10^{-5}λ^{-6}+3.1007606\text{×}10^{-6}λ^{-8}$$

Comments

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