Newton used a concave spherical mirror to make his reflecting telescope, a design that is still popular with amateur astronomers due to its simplicity, low cost and high degree of image quality ...
These mirrors, which could be scaled up to the sizes needed in space telescopes, were created by using chemical vapor deposition to grow membrane mirrors on a rotating liquid inside a vacuum chamber.
Mike Every knows about grinding glass—and he doesn’t like it. The second-year physics major from Saugerties, N.Y., is an amateur telescope maker with an idea for producing lightweight mirrors out of ...
The Giant Magellan Telescope’s third primary mirror will be unveiled at the University of Arizona’s Steward Observatory Mirror Lab on December 6, 2013 ...
The concrete is then "spincast" to form a parabolic bowl-shape characteristic of a telescope mirror. Chen then put the bowl into a vacuum chamber and applied a thin coating of aluminum to form a 0 ...
The model itself employs a 4.5-inch main parabolic mirror set in an open ribbed cage. The equatorial mounting has a spring wound drive. According to its donor it was constructed between 1913 and 1915 ...
Super-thin ‘mirror membranes’ could lead the way to bigger space telescopes The lightweight, flexible material could one day produce telescope mirrors even larger than JWST's. By Andrew Paul ...
And among the competing projects, the next simplest had more than 500 primary mirror segments (that’s the 30 m telescope) and the European project had even more than that: 700 – 800 segments.
Researchers have developed a new way to produce and shape large, high-quality mirrors that are much thinner than the primary mirrors previously used for telescopes deployed in space. As described ...
