Dispersion formula

$$n^2=3.055125-1.2150543\text{×}10^{-2}λ^{2}+3.8382477\text{×}10^{-2}λ^{-2}+3.2031384\text{×}10^{-3}λ^{-4}-2.4096955\text{×}10^{-4}λ^{-6}+2.9674918\text{×}10^{-5}λ^{-8}$$

Comments

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