Measurements made on the components and on two assembled systems of a 2-m Ritchey-Chretien telescope have been used to determine the actual characteristics of the telescope. Sufficient precision has been obtained so that other focal ratio systems can be designed.
对一台2米 Ritchey - Chretien 望远镜的组件以及两个组装好的系统进行的测量，已被用于确定该望远镜的实际特性。现已获得足够的精度，以便能够设计其他焦比系统。
