Ellipsometric spectra Ψ(λ), ∆(λ) was measured for Pb₅Ge₃O₁₁ optical crystal in the spectral range 388-620 nm. Mathematical model was developed taking into account optical anisotropy and surface roughness of the measured specimen. Nonlinear regression method was applied in order to fit experimental and modeled data. Refractive index spectra no(λ) ne(λ) are determined for Pb₅Ge₃O₁₁ single crystal for ordinary and extraordinary light beams.
