The making of the Webb Space Telescope’s mirrors is a complex process. Each surface must be precisely shaped to capture and direct the maximum amount of light to the telescope’s detectors. The mirrors must be ground and polished to a smooth curve that keeps light from bouncing off in unwanted directions. Join us at Tinsley Laboratories in Richmond, Calif., where engineers are bringing Webb’s mirrors to their exact requirements.
