Dispersion formula

$$n^2=2.9752450-1.4250160\text{×}10^{-2}λ^{2}+2.1400740\text{×}10^{-2}λ^{-2}+9.7553370\text{×}10^{-4}λ^{-4}-6.9795300\text{×}10^{-5}λ^{-6}+4.1149240\text{×}10^{-6}λ^{-8}$$

Comments

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