Dispersion formula

$$n^2=2.5571053-9.8775595\text{×}10^{-3}λ^{2}+2.1541945\text{×}10^{-2}λ^{-2}+1.0997608\text{×}10^{-3}λ^{-4}-4.8568692\text{×}10^{-5}λ^{-6}+5.601559\text{×}10^{-6}λ^{-8}$$

Comments

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