Designing, specifying, mounting, and aligning an 800-mm lens for an 8-m-class prime focus corrector

We report on the status of an on-going project for the realization of two prime focus imaging cameras for the Large Binocular Telescope. Each channel is optimized for a specific wavelength range, namely the blue and the red portions of the visible spectrum. One of the most challenging parts of the instrument, concerning optical design and mounting issues, is represented by the optical correctors required to balance the aberrations induced by the parabolic primary mirrors, over a 0.5 degree full field of view.
