FY-OPC automatically determine optical constants of materials using transmittance and reflectance spectra Software determine analyze all optical constants

OPTICAL CONSTANTS ANALYSIS AND RESULTS ANALYSIS OF COMPLEX REFRACTIVE INDEX

n*(ω)=n(ω)+Iк(ω)

Refractive index-wavelength plot (n-λ) Extinction coefficient –wavelenght (к-λ)

ANALYSIS OF DIELECTRIC CONSTANTS

ε(ω)=εr(ω)+iεi(ω)

Reel part of dielectric constant –wavelenght (εr-λ) Imaginary part of dielectric constant –wavelenght (εi-λ)

σ(ω)=σr(ω)+iσi(ω)

Reel part of optical conductivity –wavelenght (σr-λ) Imaginary part of optical conductivity –wavelenght (σi-λ)
