Dispersion formula

$$n^2=3.1735908-1.4865209\text{×}10^{-2}λ^{2}+2.954021\text{×}10^{-2}λ^{-2}+9.8366596\text{×}10^{-4}λ^{-4}-2.2979104\text{×}10^{-5}λ^{-6}+3.8043975\text{×}10^{-6}λ^{-8}$$

Comments

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