Dispersion formula

$$n^2=2.8255229-1.3632902\text{×}10^{-2}λ^{2}+1.9791402\text{×}10^{-2}λ^{-2}+1.5032564\text{×}10^{-5}λ^{-4}+4.0761368\text{×}10^{-5}λ^{-6}-1.7527267\text{×}10^{-6}λ^{-8}$$

Comments

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