title: Two-step method for lens system design.
abstract: This paper proposes a method for lens system design. It consists of two main steps called Glass-Selection Step and Further-Optimization Step. We modify coordinate-wise algorithm to obtain the glass combination in Glass-Selection Step. In Further-Optimization Step, we use modified coordinate-wise algorithm combined with modified evolutionary algorithm to find out the optimal solution. We succeed in obtaining high quality design with the proposed method.
