Wolter type II telescope

Target entity: Wolter type II telescope
Context triple: [Wolter type I grazing-incidence telescope, hasVariant, Wolter type II telescope]

• A. Cassegrain telescope
  A Cassegrain telescope is a reflecting telescope design that uses a combination of a primary concave mirror and a secondary convex mirror to fold the optical path and produce a compact instrument with a long effective focal length.
• B. Schmidt telescope
  A Schmidt telescope is a wide-field reflecting telescope design that uses a spherical primary mirror and a correcting lens to capture sharp images over a large area of the sky.
• C. Schmidt–Cassegrain telescope design
  The Schmidt–Cassegrain telescope design is a compact catadioptric optical system that combines a spherical primary mirror with a Schmidt corrector plate to provide long focal lengths in a short, portable tube widely used in amateur and professional astronomy.
• D. Maksutov–Cassegrain telescope design
  The Maksutov–Cassegrain telescope design is a compact catadioptric optical system that uses a spherical primary mirror and a meniscus corrector lens to provide long focal lengths with well-corrected, high-contrast images in a relatively short tube.
• E. Wolter type I grazing-incidence telescope
  A Wolter type I grazing-incidence telescope is a specialized X-ray imaging system that uses nested, shallowly angled mirror surfaces to focus high-energy X-ray photons that would otherwise penetrate or be absorbed by conventional optical mirrors.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Wolter type II telescope
Target entity description: The Wolter type II telescope is a specialized grazing-incidence X-ray telescope design that uses a combination of parabolic and hyperbolic mirror segments arranged differently from the type I configuration to focus high-energy radiation.
