Target entity: Schmidt camera
Context triple: [Palomar 18-inch Schmidt Telescope, hasOpticalDesign, Schmidt camera]
  • A. Korsch three-mirror anastigmat
    The Korsch three-mirror anastigmat is a specialized reflective telescope design using three mirrors to provide a wide, well-corrected field of view with minimal optical aberrations, making it ideal for high-precision space observatories.
  • B. Schmidt telescope chosen
    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. Baker–Nunn camera
    The Baker–Nunn camera is a specialized wide-field tracking telescope system developed in the mid-20th century for highly accurate photographic observation of artificial Earth satellites.
  • D. 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.
  • E. 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.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
