Dispersion formula

$$n^2=2.8747114-1.2071704\text{×}10^{-2}λ^{2}+2.228392\text{×}10^{-2}λ^{-2}-2.9355832\text{×}10^{-4}λ^{-4}+8.2863813\text{×}10^{-5}λ^{-6}-3.5482876\text{×}10^{-6}λ^{-8}$$

Comments

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