Reduction of the distortion of diffractive-gradient-index high-resolution objectives.
The possibility of multiple reductions of the distortion of high-resolution monochromats that consist of diffractive and radial gradient-index lenses is shown. The desirable effect is achieved by mutual compensation of various order members. Design parameters and the field performances of objectives that confirm the effectiveness of a method, are presented.
