You can calculate reflection coefficient using Fresnel equations: http://en.wikipedia.org/wiki/Fresnel_equations" see also: http://reflectioncoefficient.info/"

Thanks! You can check also an advanced version of the site: http://dispersion.info/"

Permittivity is a function of wavelength (frequency). 80.4 value is valid for microwave diapason, not for optical one. For optical frequencies you should calculate permittivity from refractive index, i.e. \epsilon_r = n^2 To find accurate value of n at a particular wavelength in optical...

You can find dispersion curves (refractive index as a function of wavelength) for many materials on http://refractiveindex.info/"
