Dispersion formula

$$n^2=2.8125316-1.2915271\text{×}10^{-2}λ^{2}+1.9960339\text{×}10^{-2}λ^{-2}+1.9877888\text{×}10^{-4}λ^{-4}+1.7647061\text{×}10^{-5}λ^{-6}-4.4767632\text{×}10^{-7}λ^{-8}$$

Comments

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