logX   logY   eV

Dispersion formula

$$n^2=3.1789596-1.6376966\text{×}10^{-2}λ^{2}+2.5061101\text{×}10^{-2}λ^{-2}+1.231105\text{×}10^{-3}λ^{-4}-9.1803635\text{×}10^{-5}λ^{-6}+5.9965473\text{×}10^{-6}λ^{-8}$$

Comments

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