  • Many photographers prefer a catadioptric lens for its ability to capture sharp images with minimal distortion.
  • catadioptric lens
  • catadioptric designs

Examples

  • Catadioptric lens designs bear no resemblance to any other photographic lens.

    Academic text (1994)
  • The light from the scanning mirror is reflected into a Newtonian, catadioptric telescope system with a primary mirror and a lens to correct aberrations.

    Academic text (2000)
  • Large images can also be produced by the lighter and more compact catadioptric or mirror lenses, which will be covered later.

  • A second refractive material may also be useful in catadioptric designs to reduce the design constraints imposed by a single refractive material.

    Academic text (2001)
  • Catadioptric lenses have several of the same problems in use as do the very long focal-length all-glass lenses.

    Academic text (1994)
  • Their optics are catadioptric, including a partial reflector, a full reflector, and refractive elements.

    Academic text (2001)
  • Proposed designs for catadioptric exposure systems use an off-axis optical system, a central obscuration optical system, or a polarizing beamsplitter cube configuration.

    Academic text (2001)
  • A catadioptric telescope combines both mirrors and lenses, making it easier to focus light for clearer distant views.

Morphology

catadioptric = dioptric (semi-transparent) = cata + dioptric

The formation is a prefixation of 'dioptric' with the combining form 'cata-', but both elements are specialized technical terms unlikely to be known by an average B1 learner.

Etymology

Catadioptric comes from Greek parts catoptr- 'mirror' and dioptr- 'to see through or bend light', so it literally names systems that use both mirrors and lenses to direct and focus light.
