Testing large-aperture and long-focal length optical system needs proper large-aperture and long-focal length collimator. The manufacturing of the large collimator with long focal length is different from that of the large collimator with short one. The environmental condition and the mounting method of the mirror influenced the quality of collimator. In order to get a good quality of the collimator
the surface figure of the mirror must be good
and the mechanical construction for adjusting the mirror must be smart. In this paper
we introduced how to support and adjust the large primary mirror and its influence on the surface figure of the mirror. By testing
the method of supporting and adjusting has been proved right. We have already got the collimator with ideal diffraction limit.
