Here is one of the LROC NAC cameras in the cleanroom at Malin Space Science Systems in 2008. We're looking down the baffle tube. The white silver sickle-like form is the primary mirror of the optics. The small golden circle is the backside of the secondary mirror which reflects incoming light back out. Also visible on the right is a spectroradiometer used for calibrations.
