Dispersion formula

$$n^2=2.8178044-1.0126306\text{×}10^{-2}λ^{2}+2.0989819\text{×}10^{-2}λ^{-2}+6.0692316\text{×}10^{-4}λ^{-4}-2.1975044\text{×}10^{-5}λ^{-6}+2.0172856\text{×}10^{-6}λ^{-8}$$

Comments

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