In this paper, the calculation of dipole field's deflection aberration for extra-large deflection angle and the analysis of high term of a for deflection aberration have been made, a conclusion is drown that the high term of a for extra-large deflection angle is not negligible. 通过计算超大偏转角下二极场的偏转像差,对偏转像差中α高次项进行了分析,得出了超大偏转角下α高次项不应忽略的结论。
It has been shown that when the deflection angle is larger than 120 °, the effects of the third-order curved axes aberration must be considered. 结果表明,随着偏转角的增大,曲轴三级象差的影响亦增大.当偏转角大于120°时,必须考虑曲轴三级象差的作用。
The influence of aperture angle for illumination light on uniformity of the color splitting system is discussed and a color aberration correction by means of wedge coating with. gradient thickness is proposed, thus the color uniformity can be obviously improved. 讨论了照明光孔径角对分色系统色均匀性的影响,提出了用厚度渐变的楔形膜校正色差的方法,使色均匀性得到显著改进。
