Dispersion formula

$$n^2=3.0594160-1.5171267\text{×}10^{-2}λ^{2}+3.6396337\text{×}10^{-2}λ^{-2}+3.6902359\text{×}10^{-3}λ^{-4}-3.1750636\text{×}10^{-4}λ^{-6}+3.4272301\text{×}10^{-5}λ^{-8}$$

Comments

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