光学系统消高级球差与“高级球差补偿器”

Correcting High-grade Spherical Aberration in Optical System and High-grade Spherical Aberration Compensator

利用衍生球差消高级球差,这种在理论上尚未被大家所注意的方法,作者认为、是大相对孔径的望远、照相投影物镜及其他一些系统消高级球差的最重要的方法。文中将产生二级衍生正球差(消二级球差所必需)的情况分为十种,据此对几种典型的镜头消球差的状况作出了解释。文章最后介绍了一种能产生大量的二级衍生正球差的“高级球差补偿器”,并提供了一个应用该补偿器使一个大象差系统成为一个高象质系统的例子。

High-grade spherical aberrations are balanced by variant spheri- cal aberration, but this method bas never been noticed in theory so far. The writers consider it as a best and important way to correct high-grade spheri- cal aberrations of a big aperture object-glass of telescope, camera and other op- tical instruments. In the paper, the circumstances that cause second-grade va- riant positive aberration necessary for correcting second-grade spherical aber- ration are divided into ten kinds. An explanation of high-grade spherical aber- ration correcting of some lenses is given. The writers present a kind of 'high- grade aberration compensator' which can bring about a large amount of second- grade positive aberration and an example of utilizing the compensator to make a large aberration optical system turn into a good quality lens.
