In June 2018 at Arizona Optical Systems (AOS), the L2 lens for the LSST Camera successfully completed a bonding process that attached the lens to the pads that will mount to the composite ring of the L1-L2 assembly. The assembly is the mechanical structure that holds the L1 and L2 lenses, maintaining the correct separation between the two. Chuck Claver and Kevin Reil visited AOS to inspect the L2 lens on June 20, 2018.
