英文摘要	As for the conventional off-axis telescope system structure, the primary and secondary mirror are mostly fixed. The alignment process lacks adjustment mechanism. In addition, the off-axis system has no rotational symmetry which increases the difficulty of alignment and makes the cycle longer. In order to solve the above problems, an off-axis telephoto system structure is designed. The primary mirror has a four degree-of-freedom adjustment mechanism can be fine-tuned manually. The secondary mirror is driven by 6-aixs motion hexapod electrically. At the same time, perturbation analysis is carried out for this optical system. The sensitivity matrix between misalignments of second mirror and aberration coefficients is obtained. Based on the matrix, adjustment strategy is proposed [1-9]. Finally, the effectiveness of the designed structure and adjustment strategy is verified by experiments.The detailed process is described below. © COPYRIGHT SPIE.
