Derived optical constants

logX   logY   eV

Dispersion formula

$$n^2=2.7102301-1.0851642\text{×}10^{-2}λ^{2}+2.9534854\text{×}10^{-2}λ^{-2}+4.1107114\text{×}10^{-4}λ^{-4}+9.7348452\text{×}10^{-5}λ^{-6}+8.8402787\text{×}10^{-7}λ^{-8}$$

Comments

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