Polarized terahertz transmittance and infrared reflectivity measurements were performed on selected lead zirconate crystals at T= 10 K. Fit of the spectra enabled us to obtain all three principal components of its anisotropic dielectric function and the corresponding parameters of the polar phonon modes.
