The James Webb Space Telescope (JWST) is equipped with a primary mirror composed of 18 hexagonal segments made of lightweight beryllium. These segments work together to form a 6.5-meter (21.3-foot) primary mirror, which is significantly larger than the mirrors of previous space telescopes. The primary mirror's increased size enables the JWST to gather more light and observe fainter objects with greater precision than ever before.

The mirror segments are coated with a thin layer of gold, which allows them to effectively reflect infrared light. This feature is essential for the JWST's primary mission, which focuses on observing distant cosmic objects and studying the universe's earliest galaxies and the formation of stars and planetary systems.

The development and construction of the JWST's primary mirror involved innovative engineering and precision manufacturing techniques to ensure the mirror's accuracy and durability in the extreme conditions of space. The primary mirror's advanced design and capabilities are poised to revolutionize our understanding of the universe and provide invaluable insights into the cosmos.
