Paper Abstract

Hybrid lens is a classic two-spherical glass lens with a diffractive microstructure deposited on one of its surfaces. The imaging properties of such lens depend on four parameters: two radii of curvature of both surfaces constituting two-spherical and two parameters describing the geometry of diffractive microstructure. The III-order aberration coefficients depend explicit on those parameters. Additionally the location of input pupil alters also the expression for aberrations. By proper choice of the said parameters it is possible to construct achromatic hybrid lens with corrected spherical aberration and coma, astigmatism or field curvature alternatively. In the paper we present the algorithm of necessary calculations and illustrate the results with such image characteristics as spot diagrams, wave aberrations or point spread function of the exemplary lenses.
