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...

A holiday delivery from NASA Johnson (Dec 14th, 2015) of JWST's Aft Optics Subsystem.
The AOS is at the center of JWST's primary mirror; light is sent there by the secondary mirror. In the AOS is JWST's tertiary mirror. From there light is sent via pick-off mirrors to our instruments.
