Hybrid imaging surface is an optical surface separating two media of different refraction indices with a diffraction structure deposited on it. We assume that diffraction structure has geometry identical with an interference pattern generated by interference of two spherical waves. For such a surface we found formulae expressing location of meridional and sagittal foci of astigmatic ray pencil, analogous to s- and t-tracing formulae known in the case of the purely refractive surface. We used the said formulae for correction of astigmatism/field curvature of hybrid lens by appropriate shift of input pupil.
