title: Optical characteristics of the UNAM 2-m Ritchey-Chretien telescope.
abstract: 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.
