Dispersion formula

$$n^2=2.8876161-1.1322406\text{×}10^{-2}λ^{2}+2.3462066\text{×}10^{-2}λ^{-2}+8.7915578\text{×}10^{-4}λ^{-4}-3.9372724\text{×}10^{-5}λ^{-6}+4.4353174\text{×}10^{-6}λ^{-8}$$

Comments

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