Coatings

FRED supports numerous coating types:

• Bare, uncoated surface • User-defined table of transmission and reflection coefficients (amplitude and phase) as a function of wavelength • User-defined table of S-state and P-state reflection and transmission coefficients (amplitude and phase) as a function of wavelength and angle of incidence • Quarter-wave coating • Thin film layer prescription (supports groups of layers • Jones matrix (idealized) polarization/waveplate model

Reflection vs. angle of incidence plot showing both polarization states and average Polarization coating created from sampled data

Quarter-wave and general thin film layer prescriptions may be composed of dispersive dielectric and/or absorbing materials. Materials may be specified from glass vendor catalogs, from tabulated input of refractive indices (real and/or imaginary parts), or from a user-defined dispersion equation.
