In this lab, optical fabrication and testing takes place. It is currently being run by world-class optician, Dave Hilyard, and assisted by Brian Dupraw.
In 2006, the Optics and Instrument Shops re-aluminized the 120" mirror of the Shane Telescope at Lick Observatory. See the step-by-step report here.
Dave and Brian travel to Mt. Hamilton on a regular basis to assess and clean the optics, not just on the telescopes but on all of the instruments as well. See the reports here.
