Caption: LBT mirror. Technicians check the mirror for the Large Binocular Telescope (LBT). This 8.4-metre mirror is the largest ever cast for a telescope. The mirror is made of 15.6 tonnes of borosilicate glass and its honeycomb design makes it strong but light. It was cast by a process of melting, moulding & spinning in a rotating oven. The mirror is then finely polished. Two identical mirrors will be placed on a common mount in the LBT on Mount Graham in Arizona, USA. Together they will have the light-collecting power and image sharpness of a much larger single mirror. Photographed in 1997 at the University of Arizona Mirror Laboratory in Tucson, USA.
