Dispersion formula

$$n^2=3.1633746-1.3276280\text{×}10^{-2}λ^{2}+3.1133309\text{×}10^{-2}λ^{-2}+8.3523380\text{×}10^{-4}λ^{-4}+2.9980499\text{×}10^{-6}λ^{-6}+2.5568853\text{×}10^{-6}λ^{-8}$$

Comments

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