Phrase: Korsch three-mirror anastigmat | Statement: [Euclid spacecraft, telescopeType, Korsch three-mirror anastigmat]

Target entity: Korsch three-mirror anastigmat
Context triple: [Euclid spacecraft, telescopeType, Korsch three-mirror anastigmat]

• A. Carl Zeiss Tessar
  Carl Zeiss Tessar is a classic high-quality photographic lens design, renowned for its sharpness and compact construction and widely used in cameras and mobile devices.
• B. Maksutov telescope
  A Maksutov telescope is a compact catadioptric reflecting telescope that uses a meniscus corrector lens to deliver sharp, well-corrected images with relatively simple alignment and maintenance.
• C. 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.
• D. 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.
• E. Schmidt corrector plate
  A Schmidt corrector plate is a specially shaped aspheric lens used at the entrance of Schmidt-type telescopes to correct spherical aberration and produce a wide, well-corrected field of view.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
