Abstract
The design of a four-spherical-mirror zoom telescope is presented. By use of third order aberration theory the system is determined to satisfy the aplanatic condition at every point on the zooming locus. From examination of spot diagrams, a system with Cassegrainian-Cassegrainian configuration is found satisfactory. The design data are presented.
