Optical constants of In2O3-SnO2 (Indium tin oxide, ITO)
König et al. 2014: EMA layer; n,k 0.25-1.0 µm

Wavelength: µm
 (0.25157 – 1)  

Derived optical constants

n   k   logX   logY   eV


Optical constants of roughness layer (effective medium approximation (EMA) layer), thickness d=2nm, add this layer to ITO refractive index layer (setup: BK7+ITO(d=72nm)+EMA(d=2nm)), ITO purchased from Delta Technology (CG-60IN-CUV), 15-25 ohms, ITO on BK7. ITO includes a separate roughness layer (see EMA)
