Abstract
The idea of a principal surface of an optical system is discussed in terms of its construction and possible utility. The construction can be applied to real optical systems and uses real, as opposed to paraxial, rays. The concept of a principal surface is applied to the Cassegrain telescope, and it is shown that the locus of object-space principal points forms a paraboloid surface. This paraboloid can be used to represent at least the axial properties of the Cassegrain.
