以像差理论为指导分析了混合望远物镜中二元光学透镜与转像棱镜之间的像差补偿问题.计算了二元光学器件的相位系数,确定了含补偿棱镜望远物镜的初始结构.用CODEV光学设计软件对望远物镜初始结构优化后的像差结果表明:系统色差在0.9相对孔径高度得到了校正,纵向球差在容限范围0.5mm之内,最大横向误差为-0.115mm.
Under the guidance of aberration theory, the problem of aberration compensation between binary optical lens and transfer prism in hybrid telescope is analyzed. The phase coefficient of binary optics is calculated and the initial structure of the telescope with compensating prism The optical aberration results of CODEV optical design software on the optimized initial structure of the telescope showed that the system chromatic aberration was corrected at the relative aperture height of 0.9, the longitudinal spherical aberration was within the tolerance range of 0.5 mm and the maximum lateral error was -0.115 mm .
