在三阶像差理论的基础上，对二圆锥反射消球差透镜的性质进行了分析和讨论。开发了设计无限共轭两镜消球差并计算其图像特性的技术。检查了里奇-克雷蒂安望远镜和消球差格里高利望远镜的副镜对准特性，并定义了中性点位置。确定了针对第三种赛德尔像差（像散、图像曲率或畸变）进行校正的设计配置，并讨论了它们的特性。比较了里奇-克雷蒂安望远镜和消球差格里高利望远镜的特性。
The properties of two-conic reflecting aplanats are analyzed and discussed on the basis of third order aberration theory. Techniques for designing infinite conjugate two mirror aplanats and computing their image properties are developed. The secondary mirror alignment characteristics of Ritchey-Chrétien and aplanatic Gregorian telescopes are examined and neutral point locations defined. Design configurations corrected for a third Seidel aberration (astigmatism, image curvature, or distortion) are identified and their properties discussed. The properties of Ritchey-Chrétien and aplanatic Gregorian telescopes are compared.
