Dispersion formula

$$n^2=2.6515563-1.0678481\text{×}10^{-2}λ^{2}+1.708672\text{×}10^{-2}λ^{-2}-9.2823421\text{×}10^{-5}λ^{-4}+6.0970481\text{×}10^{-5}λ^{-6}-3.5490225\text{×}10^{-6}λ^{-8}$$

Comments

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