Abstract: The Large Binocular Telescope (LBT) uses two 8.4 m diameter primary mirrors mounted side-by-side to produce a collecting area equivalent to an 11.8 m circular aperture. A unique feature of LBT is that the light from the two primary mirrors can be combined to produce phased array imaging of an extended field. This coherent imaging along with adaptive optics gives the telescope the diffraction-limited resolution of a 22.65 m telescope. First light with a single primary mirror and a prime focus imager was achieved in 2005 October. The second of two 8.4 m borosilicate honeycomb primary mirrors was installed in the telescope in 2005 October and was aluminized in 2006 January. Binocular operation with two prime focus cameras is planned for early 2007. The telescope will use two F/15 adaptive secondaries to correct atmospheric turbulence. These adaptive mirrors are now being integrated with their electromechanics.
