摘要
采用衍/折射光学元件结合的方法,使用两种玻璃设计了星载用长焦距望远物镜,对其二级光谱进行了校正。具体介绍了衍/折透镜望远透镜消二级光谱方法、步骤。计算机模拟结果表明:校正后的望远物镜轴上位置色差小于0.08mm,满足使用要求,并且设计方法步骤简单。
Binary optics can be used to increase optical performances,decrease size and weight,and decrease systems costs in numerous applications.By means of hybrid diffractive-refractive,using two kind of glasses,a method and processes of apochromats have been introduced to realize decreasing secondary spectrum in long focus telescope for secondary planet in detail.The research results show that secondary spectrum doesn't affect the quality of sight field in the corrected telescope.The correction method is simple and satisfiable.
