`Aplanatic' Wolter Type I telescope design: Is there a practical advantage?

Abstract

For the relatively new field of X-ray/EUV astronomy, the Wolter Type-I and Wolter Type-II grazing incidence telescope designs are extensively utilized. `Aplanatic' versions of both types of telescopes are widely touted as being superior designs. However, scattering effects and other practical optical fabrication tolerances prevent these grazing incidence telescope designs from being near diffraction-limited at the X-ray/EUV wavelengths. Comparison of performance predictions for the classical versus `aplanatic' Wolter Type-I X-ray telescopes is discussed for the special case of the solar X-ray imager (SXI).
