Dispersion formula

$$n^2=3.2618526-1.5375794\text{×}10^{-2}λ^{2}+3.3152898\text{×}10^{-2}λ^{-2}+1.4090033\text{×}10^{-3}λ^{-4}-5.5295605\text{×}10^{-5}λ^{-6}+7.1360367\text{×}10^{-6}λ^{-8}$$

Comments

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