This place makes big optics! One of the 8.4 meter primaries for the Large Binocular Telescope (LBT) sits behind Debra and optician Roger Ceragioli. Dean Ketelsen is standing on a 6.5 meter primary for a Lockhead Martin Corporation project in the back. We have often visited our friends at the lab. It's always exciting to see what they are making.

Roger and Debra with the mirror lab's giant red mirror cell that holds and moves the mirrors around as they make them. This was used to make the big 8.4 meter primaries for the LBT.
