Paper Abstract

Optical hybrid systems, i.e., systems containing the optical elements of different types (diffractive and gradient-index lenses), are considered. The correction possibilities of two- and three-element hybrid objectives are analyzed. It is shown that the two-element objective may be corrected for all monochromatic third-order aberrations. As a result the space frequency of diffractive lens structure and the magnitude of the refractive index change of gradient-index lens can be decreased. Various fifth-order aberrations can also be corrected. This objective forms a high resolution image and wide linear field in the image space. The three-element hybrid objective consists of one diffractive and two gradient-index lenses. This objective has a symmetric configuration and unit magnification. It is shown that in such an objective, which is free from all third-order aberrations, it is possible to eliminate simultaneously three out of four different fifth-order aberrations. In particular, this result remains valid if the optical power of the diffractive element is equal to zero. The design of a three-element hybrid objective is reported. The resulting designs are compared with homogeneous objectives.
