Dispersion formula

$$n^2=3.0731081-1.5043205\text{×}10^{-2}λ^{2}+2.3933518\text{×}10^{-2}λ^{-2}+5.5696651\text{×}10^{-4}λ^{-4}-1.0082346\text{×}10^{-5}λ^{-6}+1.1873265\text{×}10^{-6}λ^{-8}$$

Comments

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