Active Optics -- Active optics is a relatively new technology for astronomic telescopes. Most modern telescopes are reflectors, with the primary element being a very large mirror. Historically, a fixed weight-to-diameter relation was used to build these mirrors, limiting their maximum diameter to 5 or 6 meters (200 or 230 inches), like in the Palomar Observatory. A new generation of telescopes uses instead very thin mirrors, uncapable of sustaining themselves. Instead, an array of...

Credit: Denys/Wikipedia (CC BY-SA 3.0) The Subaru Telescope is a 26.9-foot (8.2m) telescope located at the Mauna Kea Observatory on the Big Island of Hawaii and operated by the National Astronomical Observatory of Japan (NAOJ). It had the largest primary mirror in the world until 2005. This is a reflecting telescope with a large field of view--called a Ritchey-Chretien--which has a primary mirror and a secondary...

Keck Observatory -- From a remote outpost on the summit of Hawaii's dormant Mauna Kea volcano, astronomers at the W.M. Keck Observatory probe the deepest regions of the Universe with unprecedented power and precision. Their instruments are the twin Keck Telescopes, the world's largest optical and and infrared telescopes. Each stands eight stories tall and weighs 300 tons, yet operates with nanometer precision. At the heart of each Keck Telescope is a revolutionary primary mirror. Ten...
