The authors describe characteristics and key results of the optical design for adaptive optics at the Galileo telescope. Two off axis parabolae are used to image the pupil on the deformable mirror, and in order to keep to a minimum the number of reflections, one of them is used as tip-tilt mirror. The several constraints, both mechanical and optical, which led to the definitive design are reported (pupil position, effective focal ratio, off axis performances, size of the module . . .). Because tip-tilt is realized through tilting of a non-flat mirror care has been given to the deterioration and distortion of the image for a given range of misalignment of the off axis parabola.
