We congratulate NASA and all involved in the James Webb Space Telescope (JWST) on their successful launch and mission objective!
Engis Corporation technology has contributed to the powerful cutting-edge technology that is enabling the recently launched James Webb Space Telescope to answer questions about our solar system, study exoplanets in new ways, and look deeper into the universe than we've ever been able to.
Much of what powers JWST’s ability to see deep into space comes from its 21-foot-wide primary mirror which is comprised of 18 segments made from Beryllium.
Beryllium is a light metal that is very strong for its weight and is good at holding its shape across a range of temperatures. Because beryllium is very difficult to grind and polish, diamond machining processes were used to fabricate the mirror segments. Before the segments were coated with a thin layer of gold the segments were polished by L3 Tinsley Laboratories using specially developed Engis diamond abrasive products.
