Dispersion formula

$$n^2=2.8205467-1.0789821\text{×}10^{-2}λ^{2}+2.6216351\text{×}10^{-2}λ^{-2}+3.4058709\text{×}10^{-4}λ^{-4}+4.6765010\text{×}10^{-5}λ^{-6}+6.6030419\text{×}10^{-7}λ^{-8}$$

Comments

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