Dispersion formula

$$n^2=2.6658188-1.5222706\text{×}10^{-2}λ^{2}+1.7138042\text{×}10^{-2}λ^{-2}+2.6165294\text{×}10^{-3}λ^{-4}-2.7592859\text{×}10^{-4}λ^{-6}+1.8035723\text{×}10^{-5}λ^{-8}$$

Comments

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