Third-order aberrations of an AGRIN thin lens as a function of the shape and conjugate variables

摘要

This work presents the expressions for the third-order aberrations of a thin lens in air made with an axial gradient index material (AGRIN). These are derived from those corresponding to two homogeneous plano-aspheric thin lenses, with the piano surface in contact, as it has been proposed. Further, they have been expressed as a function of the shape factor, B, and conjugate variable, C, to be consistent with those previously published considering other thin-lens cases. Simple examples of their suitability for obtaining a third-order system predesign are shown.
