Two smectic phases of an achiral smectic liquid crystal, Sm-C1 and Sm-C2, were investigated on free standing films. The optical properties of the liquid crystal were investigated using null transmission ellipsometry and depolarized reflected light microscopy (DRLM). It was observed that the molecular orientation in the Sm-C1 and Sm-C2 phases was synclinic and anticlinic respectively. DRLM enabled to visualize the c-director, the projection of average long axes of molecules onto the layer plane and of tilted smectic phases in thin free-standing films.
