Derived optical constants

logX   logY   eV

Dispersion formula

$$n^2=2.4465754-1.0107041\text{×}10^{-2}λ^{2}+1.7759132\text{×}10^{-2}λ^{-2}+8.7970259\text{×}10^{-4}λ^{-4}-5.7014929\text{×}10^{-5}λ^{-6}+6.0924663\text{×}10^{-6}λ^{-8}$$

Comments

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