Abstract

We present here the results obtained from a Shack-Hartmann analysis of the optical quality of the primary mirror of the Telescopio Nazionale Galileo. We compare our results with those obtained from Zeiss from interferometry, finding a good agreement. The 80% encircled energy is found to be within a diameter of 0.14 arc sec. Calculations of the MTF, EE and PSF and comparison with diffraction theory show a remarkable agreement, indicating that the mirror quality is very near the diffraction limit.
