Dispersion formula

$$n^2=2.8106459-1.0211215\text{×}10^{-2}λ^{2}+2.047301\text{×}10^{-2}λ^{-2}+9.7897189\text{×}10^{-5}λ^{-4}+3.378933\text{×}10^{-5}λ^{-6}-1.1893964\text{×}10^{-6}λ^{-8}$$

Comments

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