Designing Lenses with a Computer

C. A. Lehman

Designing a lens with a computer requires that all the data which describe the lens specifications be fed to the computer as numbers. Features of such a computer program are described. Ray tracing is employed to evaluate a merit function, defined as the sum of the squares of the weighted ray deviations from the centroid of the image element. An iterative procedure is used to find lens parameter values which minimize the merit function.
