Dispersion formula

$$n^2=3.1508338-1.2524775\text{×}10^{-2}λ^{2}+2.9840102\text{×}10^{-2}λ^{-2}+5.2842784\text{×}10^{-4}λ^{-4}+3.3351662\text{×}10^{-5}λ^{-6}+1.251841\text{×}10^{-7}λ^{-8}$$

Comments

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