Dispersion formula

$$n^2=2.4196645-8.3329314\text{×}10^{-3}λ^{2}+1.5397390\text{×}10^{-2}λ^{-2}-1.7391654\text{×}10^{-4}λ^{-4}+6.2183220\text{×}10^{-5}λ^{-6}-3.0621310\text{×}10^{-6}λ^{-8}$$

Comments

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