Spin-orbital interaction of light attracts much attention in nanophotonics opening new horizons for modern optical systems and devices. The photonic spin Hall effect or Imbert-Fedorov shift takes a special place among the variety of spin-orbital interaction phenomena. It exhibits as a polarization-dependent transverse light shift usually observed in specular scattering of light at interfaces with anisotropic materials. Nevertheless, the effect of the polarization mixing caused by anisotropy on the Imbert-Fedorov shift is commonly underestimated. In this work, we demonstrate that polarization mixing contribution cannot be ignored for a broad range of optical systems. In particular, we show the dominant influence of the mixing term over the standard one for the polarized optical beam incident at a quarter-wave plate within the paraxial approximation. Moreover, our study reveals a novel contribution with extraordinary polarization dependence not observable within the simplified approach. We believe that these results advance the understanding of photonic spin Hall effect and open new opportunities for spin-dependent optical phenomena.

Optical systems developed by the authors and used for many years to study the polarization properties of anisotropic molecules are presented. Both systems are designed for visible and close to ultraviolet spectral regions. In this case, the double Fresnel parallelepiped plays the role of the achromatic quarter wave plate. They are used in the Jasco-20 dichrograph after the Pokels cell. Causing the sensitivity of the device increases from deg·sm-1 to 3 the magnitude of differences of the optical density.
