Abstract近地天体望远镜由SI600S(4k×4k) CCD升级为STA1600LN(10k×10k) CCD后,观测视场由4 deg 2增至9 deg 2,可用视场直径由望远镜原设计视场的3.14?增至4.28?,超出原设计36%,同时作为CCD密封窗的场镜增厚8.75 mm;两个因素导致10k CCD成像的轴外像差增大,视场外围的像质变差.依据望远镜原始设计光学参数,借助光学设计软件ZEMAX进行像质改善尝试,最终选择在10k CCD场镜前插入一个由两片球面透镜组成的场改正镜,使10k CCD的轴外像差得到校正.同时还提出了一个进一步拓展近地天体望远镜观测能力的设计方案,将望远镜的可用视场从目前的14.38 deg~2扩展至28.27 deg~2.
