前言照相机、望远镜以及眼镜所用的透镜,一直是用各种半径的球面和平而组成的,叫作球面透镜。经过长期的探索,确立了一套透镜的制作方法。同前可以做出相当高精度的球面透镜(可达光波长的几十分之一)。但是,无论怎样提高制作精度,单个球面透镜肯定存在着像差。因此,要制成具有更高性能的透镜,就必须配置多片的透镜和反射镜,用来补尝像差。而且,球面透镜组合时,也要受到其光学特性的限制,很难向特殊用途(宽银幕镜
Foreword Cameras, binoculars and lenses used in the lens, has been composed of various radius spherical peace, called the spherical lens. After a long period of exploration, established a set of lens manufacturing methods. The same can be done with a very high-precision spherical lens (up to a few tenths of light wavelength). However, no matter how to improve the production accuracy, there must be a single spherical lens aberration. Therefore, to produce a lens with higher performance, it is necessary to configure a plurality of lenses and mirrors to compensate for aberrations. Moreover, the spherical lens combination, but also subject to its optical characteristics, it is difficult to special purpose (widescreen mirror
