Dispersion formula

$$n^2=2.8274666-1.4568462\text{×}10^{-2}λ^{2}+1.8525487\text{×}10^{-2}λ^{-2}+3.748582\text{×}10^{-4}λ^{-4}-7.1291749\text{×}10^{-6}λ^{-6}+6.7781934\text{×}10^{-7}λ^{-8}$$

Comments

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