A segmented mirror is an array of smaller mirrors designed to act as a single, larger mirrored surface, usually used in large telescopes. Because current monolithic mirrors cannot be constructed larger than about eight meters in diameter, the use of segmented mirrors is a key component of current large-aperture telescopes. 50 cm refracting telescope at Nice Observatory. ...

The Mauna Kea Observatory, an institute of the University of Hawaii, is considered one of the most important land-based observatories in the world for its isolated, unobstructed views of space without interference from man-made light sources. ...

Proposed Segmented-Mirror Telescopes
These telescopes represent the next generation of segmented mirror telescopes; they are currently at least a decade from completion. 50 cm refracting telescope at Nice Observatory. ...
In a reflecting telescope, or reflector, light is reflected by a concave mirror and brought to a focus in front of the mirror.
The small secondary mirror, which blocks a negligible portion of the primary mirror, is tilted at an angle of 45° in order to reflect the convergent light at right angles and bring it to a focus outside the telescope tube.
Equal in importance to the mirrors and lenses constituting the optics of a telescope is the mounting of the telescope.
