1·Chromatic Aberration — usually associated with objective lenses of refractor telescopes, is the failure of a lens to bring light of different wavelengths (colors) to a common focus.

色差-经常在折射望远镜的物镜上出现，是因为透镜不能把不同波长(颜色)的光聚焦到一点而形成的。

2·This phenomenon is called a chromatic aberration; another example of this effect is seeing a rainbow when you shine white light through a prism.

这种现象叫做“色差”（chromatic aberration）；这种效应的另一个例子是，当你将白光照射棱镜时便可以看到彩虹。

3·However, for the actual optical system, its point image become a speckle because of diffraction of light and aberration.

对于实际光学系统，由于光的衍射和像差，使所成的点像为一弥散斑。

4·This paper presents a new algorithm used for fast simulating the image formation characteristics of aberration-free system with partly coherent light.

本文给出一种部分相干照明条件下元象差显微物镜成象特性的快速模拟算法。

5·Under conditions of monochromatic light and a small object, the spherical aberration was the main factor which led to measuring error of focus of thin convex lens.

在单色光、小物条件下，球差是引起薄凸透镜焦距的测量误差的主要因素。

6·Through the system optimization, the analysis of aberration and differential thermal, the designed system is simple, light weight, large aperture, long focal, and good temperature adaptability.

该系统具有结构简单、质量轻、口径大、焦距长、失真小以及良好温度适应性等特点。

7·We considered intensity distribution of light focused by a high numerical aperture lens without spherical aberration through a planar interface between materials of mismatch refractive index.
