Webb1 dec. 2024 · The gold was coated using a technique called vacuum vapour deposition. The mirrors are kept inside a vacuum chamber and a small quantity of gold is vapourised and deposited on the mirror. The thickness of the gold is just 100 nanometers. So less than 50 grams of gold was used for the entire mirror. A thin layer of glass was also … Webb3 feb. 2024 · The gold enables the mirrors of JWST to be 98% reflective in comparison to the usual 85% reflectiveness of common mirrors. The gold layers plating the mirrors of the telescope are just 1,000 atoms thick. The complete 21-foot-wide mirror was coated using only a golf ball-sized amount of gold.
