Dispersion formula

$$n^2=2.7704622-1.3431817\text{×}10^{-2}λ^{2}+1.9112769\text{×}10^{-2}λ^{-2}+1.429283\text{×}10^{-3}λ^{-4}-1.2230128\text{×}10^{-4}λ^{-6}+8.5974178\text{×}10^{-6}λ^{-8}$$

Comments

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