Dispersion formula

$$n^2=3.1212281-1.4119909\text{×}10^{-2}λ^{2}+2.6520622\text{×}10^{-2}λ^{-2}+4.0415763\text{×}10^{-4}λ^{-4}+1.4260634\text{×}10^{-5}λ^{-6}+3.164256\text{×}10^{-7}λ^{-8}$$

Comments

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