NASA'S Webb Telescope Team Completes Optical Milestone
Ball Aerospace Technician Robin Russell inspects the Webb Telescope Aft Optics Subsystem during mirror integration activities. The Aft Optics bench, made of lightweight beryllium like the mirrors, holds Webb's tertiary and fine steering mirrors. The installed, gold-coated tertiary mirror can be seen in the background.
The Aft Optics bench is the black piece that juts out of the center of the primary mirror visible in this illustration: www.flickr.com/photos/nasawebbtelescope/4809439597/in/set...
