Dispersion formula

$$n^2=2.5393255-8.7207883\text{×}10^{-3}λ^{2}+1.5909566\text{×}10^{-2}λ^{-2}+8.8163036\text{×}10^{-5}λ^{-4}+2.5876593\text{×}10^{-5}λ^{-6}-1.1733523\text{×}10^{-6}λ^{-8}$$

Comments

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