   Primary lens: The objective of a refracting telescope. Primary mirror: The objective of a reflecting telescope. Corrector plate: A full aperture negative lens placed before a primary mirror designed to correct the optical aberrations of the mirror. Schmidt corrector plate: An aspheric-shaped corrector plate used in the Schmidt telescope.

4. Optical telescope - Wikipedia

   en.wikipedia.org/wiki/Optical_telescope

   The Large Binocular Telescope at the Mount Graham International Observatory in Arizona uses two curved mirrors to gather light. An optical telescope gathers and focuses light mainly from the visible part of the electromagnetic spectrum, to create a magnified image for direct visual inspection, to make a photograph, or to collect data through electronic image sensors.

   The refracting telescope which uses lenses to form an image. [27] The reflecting telescope which uses an arrangement of mirrors to form an image. [28] The catadioptric telescope which uses mirrors combined with lenses to form an image. A Fresnel imager is a proposed ultra-lightweight design for a space telescope that uses a Fresnel lens to ...

   en.wikipedia.org/wiki/Catadioptric_system

   The Houghton telescope or Lurie–Houghton telescope is a design that uses a wide compound positive-negative lens over the entire front aperture to correct spherical aberration of the main mirror. If desired, the two corrector elements can be made with the same type of glass, since the Houghton corrector's chromatic aberration is minimal.

   One major determining factor is type of light, or particle being observed including devices referred to as "telescopes" that do not form an image or use optics. Some telescopes are classified by the task they perform; for example Solar telescopes are all designs that look at the Sun, Dobsonian telescopes are designed to be low cost and portable ...
