The two-mirror Baker corrector for a parabolic telescope mirror is a well-known, very elegant design. In some variations, both corrector mirrors are spherical. The only thing marring the beauty of this solution to providing anastigmatic performance for large parabolic telescope mirrors is that the system is difficult to baffle. An alternate two-mirror corrector is presented here-based on a different design principle-that is easy to baffle. One of the two corrector mirrors is spherical, and there is a field stop to further aid in baffling. The penalty paid is that the signs.
用于抛物面望远镜镜面的双镜贝克校正器是一种著名且非常精巧的设计。在一些变体中，两个校正镜都是球面的。为大型抛物面望远镜镜面提供消像散性能的这种解决方案的唯一美中不足之处在于该系统难以设置遮光罩。这里提出了一种基于不同设计原理的替代双镜校正器，它易于设置遮光罩。两个校正镜之一是球面的，并且有一个视场光阑以进一步辅助设置遮光罩。所付出的代价是其像差。
