Freeform surfaces are of advantage to balance the unsymmetrical aberrations  especially for the wide-field off-axis optical systems. This paper focus on an off-axis reflective optical system  which focal length is 550mm  F# is 6.5 and field of view (FOV) is 76. The system adopts some freeform surfaces. We discuss the problems we noticed in processes of design  manufacture  measurement and alignment  and the solutions. At last  the periodical research result and the expected performance are given. 2012 SPIE.
