Abstract
The Large Binocular Telescope (LBT) will provide unique observing capabilities in terms of angular resolution and field size. The Fizeau combination of the beams from the two telescope apertures produces an intermediate image which shall be imaged onto a detector array. For this purpose, we designed an optical instrument, the thermal infrared wide-field camera described below. During its design, special care was taken to properly treat the synthetic aperture. The result is a catadioptric optical system with interchangable magnifications matched to the spectral regions around 10 and 20 μm. We present the optical design along with the image analysis.
