Abstract

Among novel optical design methods axial gradient index (AGRIN) gradually evokes attention accompanying by manufacture technical maturity. In many papers AGRIN lens is equivalent to an aspheric plano-convex doublet whose curvatures and radii are AGRIN vertexes's and plane surfaces are face to face. Nevertheless the aberrations after the treatment are very drastically changing. To finding accurate equivalent relations is necessary. In our work geometric ray track and numerical calculation are done and the accurate relations of AGRIN surface to aspheric surface are achieved. At last an AGRIN singlet for rotating image is demonstrated to verify the validity of our results. A simulation is carried out through optical design software and little aberrated variety is found. After merit treatment obtained aspheric coefficients approach calculated values.
