Automatic Lens Design

Abstract

A new method for automatic lens design on electronic computer is described. An unique target point which has been used on automatic lens design procedures to define a set of target values in multi-dimensional aberration space is replaced with a domain with non-zero volume arround the target point. The volume itself defines the amount of tolerances allowed to respective aberrations. Iterative cycles are used to find the solution. In each cycle the aberrations are corrected one by one without violating the aberrations which have been corrected in the previous cycles. The iteration are continued until we can find the final solution, a set of lens parameters, which satisfies all of aberrations taken into consideration. The boundary conditions can be treated just in the same manner as aberrations. A triplet lens was presented to the program as the test of the procedure and satisfactory results were obtained.
