Paper Abstract

The general mixed optical aberration function produced by a centered lens is calculated using geometrical raytrace of three dimensional rays in conjunction with linear interpolation. This technique has proven to be an efficient tool in lens design applications where the complete aberration function is required to assess the overall dependence of image quality on the lens construction parameters. Our approach does not use the Zernike circular polynomials which limits quality assessment to specific modes. We demonstrate the efficiency of this approach by presenting numerical results characterizing the quality of a number of practical lenses. Optimum lens construction parameters are indicated by the Point Spread Function (PSF) of the optical system at the focus and the focal shift, both, calculated from the aberration function. We examine the effects of various types of lens construction parameters and materials on image quality.
