Dispersion formula

$$n^2=2.2725452-8.4104910\text{×}10^{-3}λ^{2}+1.1306843\text{×}10^{-2}λ^{-2}+3.7782297\text{×}10^{-4}λ^{-4}-2.6903423\text{×}10^{-5}λ^{-6}+1.5976489\text{×}10^{-6}λ^{-8}$$

Comments

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