26 July 1993Design of optical systems with GRIN and diffractive lenses
The optical hybrid systems, i.e. systems, containing the optical elements of different types (diffractive and GRIN lenses) are considered. The corrective scope of two- and three-element hybrid objectives are investigated. It is shown that the two-element objective may be corrected for all monochromatic 3d-order aberrations. The three-element hybrid objective, which is inverstigated here, consists of one diffractive and two GRIN lenses. This objective has symmetric configuration and unit magnification. It is shown that in such objective, free of all 3d-order aberrations, it's possible to eliminate simultaneously the three out of the four different even 5th-order aberrations.
