Dispersion formula

$$n^2=3.5044639-2.0333833\text{×}10^{-2}λ^{2}+5.3802700\text{×}10^{-2}λ^{-2}+6.2874192\text{×}10^{-3}λ^{-4}-5.6922176\text{×}10^{-4}λ^{-6}+7.3559387\text{×}10^{-5}λ^{-8}$$

Comments

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