In this paper, an optical design is presented for an anastigmatic telescope with back focal length corrected with exact ray tracing to eliminate spherical, coma, and astigmatism aberrations. The telescope is formed of three conical mirrors, two of them polished on the same substratum. The optical design is divided into three stages: we began the design obtaining the Gaussian parameters in a first-order solution; posteriorly, were obtained analytically the three mirrors' asphericity in a third-order design. The final design stage consists of the implementation of the Fermat's principle, the Abbe sine condition, and the Coddington equations for the exact correction for the three aforementioned aberrations.
本文提出了一种用于消像散望远镜的光学设计，其通过精确光线追迹校正后焦距，以消除球面像差、彗差和像散像差。该望远镜由三个圆锥面镜组成，其中两个在同一基底上抛光。光学设计分为三个阶段：我们首先在一阶解中获得高斯参数来开始设计；随后，在三阶设计中通过解析得到三个镜面的非球面性。最终设计阶段包括应用费马原理、阿贝正弦条件和科丁顿方程，以对上述三种像差进行精确校正。
