Additive manufacturing of metal mirrors for TMA telescope

Additive manufacturing enables enhanced designs for metal mirrors and housings of optical systems like telescopes. Internal lightweight structures are used for the mirror modules to reduce the weight of the system while keeping the mechanical stability. Internal structures can be produced by selective laser melting, which cannot be realized by conventional machining.

India gets world’s first liquid-mirror telescope; What is it? How will ...

This telescope's operations and maintenance will be handled by India. In early 2022, India's first liquid-mirror telescope saw its first light as it stared towards the zenith from the Devasthal observatory in Uttarakhand, observing asteroids, supernovae, space debris, and all other celestial objects at a height of 2,450 metres in the Himalayas.William Herschel, a musician who moved from Hanover to England and turned to astronomy, directed his first efforts toward building refracting telescopes. But the lengthy tubes annoyed him (he made one as long as 30 feet), and he turned his attention to mirrors. By the late 1770s, Herschel had built several reflectors.Early Reflectors (Cosmology: Tools) - AIPThe world's largest liquid mirror telescope is ready to gaze at the stars.

Mirrors Webb/NASA - Webb Space Telescope

The James Webb Space Telescope (sometimes called Webb or JWST) is a large infrared telescope with a 6.5-meter primary mirror. Webb is the premier observatory of the next decade, serving thousands of astronomers worldwide. It studies every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life ...The simplest and most common mirror coating is a thin layer of metal. A 100-nm layer of aluminum or silver makes an excellent reflector for the visible spectrum. Aluminum reflects about 90 percent of the light across the visible spectrum, while silver reflects about 95 percent. The reflectance of a metal mirror can be calculated from the index ...Mirrors: Coating Choice Makes a Difference - PhotonicsNEW. Celestron Kids 50mm Newtonian Telescope Learn More.
