Dispersion formula

$$n^2=2.2702566-9.1988101\text{×}10^{-3}λ^{2}+1.1609706\text{×}10^{-2}λ^{-2}-7.6123911\text{×}10^{-5}λ^{-4}+2.8558727\text{×}10^{-5}λ^{-6}-1.2566486\text{×}10^{-6}λ^{-8}$$

Comments

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