Abstract
An optical system resembling a modified Gregorian astronomical telescope is disclosed in the specification and drawings. Lenses are used in the inter-focal region to modify the optical characteristics of the system. The use of such inter-focal lenses, can, for example, flatten the image plane of the field thereby increasing the field of view of the telescope.
