Paper Abstract

The encircled energy of grazing incidence Wolter telescopes has been studied by application of Saha's transverse ray aberration theory. A formula has been derived for the encircled energy of the Wolter telescopes. It has been used to the calculate the encircled energy of several Wolter I and II grazing incidence telescopes. The results derived from the formula have been compared with those obtained by exact ray tracing. The effects of third, fifth, and seventh-order aberration theory have been studied.
