The mirror assembly from the front with primary mirrors attached, November 2016 The secondary mirror being cleaned with carbon dioxide snow. Optical Telescope Element (OTE) is a sub-section of the James Webb Space Telescope, a large infrared space telescope launched on 25 December 2021, [1] consisting of its main mirror, secondary mirrors, the framework and controls to support the mirrors, and ...
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.
There are always more telescopes (Spitzer, Sloan Digital Sky Survey, Pan-STARRS, solar telescopes, notable historical ones like Herschel's 40-foot telescope and the Leviathan of Parsonstown), but you have a good assortment and I don't want to clutter the diagram more. The focus seems to be showing the upcoming generation of extremely large ...
A Serrurier truss tube assembly on the Carl Zeiss Cassegrain telescope in Ostrowik near Warsaw.. A Serrurier truss is used in telescope tube assembly construction. The design was created in 1935 by engineer Mark U. Serrurier when he was working on the Mount Palomar 200 in (5.1 m) Hale Telescope. [1]

The Schmidt camera is a wide-field photographic telescope, with the corrector plate at the center of curvature of the primary mirror, producing an image at a focus inside the tube assembly at the prime focus where a curved film plate or detector is mounted. The relatively thin and lightweight corrector allows Schmidt cameras to be constructed ...
