An analytical approach to optic-axis light figures of optically active transparent materials with transversally isotropic linear dielectric function is developed. The ratio of the gyration constant to the parameter of anisotropy of this function is shown to be essential for the scale of the gyration effect on light figures. An algorithm for determination of all material-related optical parameters is proposed in the form covering both symmetries possible for optical activity in uniaxial materials, such as AgGaS2 and TeO2. For AgGaS2, a deviation of the shape of the interference curves from circular is expected at enough large angles of interference. In full agreement with the performed theoretical analysis, the shrinking of interference curves into zero-size isochromates is observed at multiples of π for rotation angle of a thick 1420 μm-plate of TeO 2. Transversal component of gyration pseudo-tensor of TeO 2: is determined for the first time. The recently proposed relative light-figure method is re-formulated and briefly discussed with allowance for optical activity.
