Dispersion formula

$$n^2=2.7201325-1.2755345\text{×}10^{-2}λ^{2}+2.235917\text{×}10^{-2}λ^{-2}+1.1060351\text{×}10^{-3}λ^{-4}-5.6019485\text{×}10^{-5}λ^{-6}+5.8998558\text{×}10^{-6}λ^{-8}$$

Comments

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