看了觉得可以，就留着作者的名字吧，这是对别人劳动的尊重 Name:獨①無〆 QQ E-mail:zengzheng2004@163.com Chapter13 13 章 Coma and astigmatism 慧差与散光 13.1 introduction 介绍 This chapter will continue the program started in chapter 10. the ZEMAX aberration table is reprised as here as figure 13.1. this time, however, attention focuses on the transverse spherical aberration, coma, and astigmatism (indicated the boxed-in regions). The aberration formulation contained in table 10.1 will be utilized to compute Seidel and wavefront coefficients for the singlet introduced in section 10.3. in this way we will obtain some insight as to the manner in which ZEMAX generates the aberration numbers displayed in the table. 这个章节将继续第 10 章的内容。 ZEMAX 像差表格如图 13.1 。 这时,注意焦点上横向球差,慧差, 并且散光(表明是 boxed-in 区域) 。像差表达式包含在表 10.1 将被用来计算 Seidel 和波前系数的单镜片在 10.3 部分有介绍. 这样我们将 获得一些见解显示在 ZEMAX 引起像差值的表格里。 13.2 Transverse spherical aberration: SA3 横向球面像差: SA3 We saw in section 11.8 that the transverse ray aberration for spherical aberration is given by: 我们看见在 11.8 部分, 横向光线像差是球差引起的: From figure 13.1 we see that W040=12.4535 λ=0m. from the first order properties shown in figure 13.2 we see that the EFL=49.0604cm, and the EPD=8cm. since the object is at infinity, R=EFL, and r=EPD/2. inserting these values into equation 13.1: 从图 13.1 我们看出 W040=12.4535 λ=0m 。 从 第一阶性质被显示在上图 13.2 我们看见 EFL=49.0604cm, 并且 EPD=8cm 。 因为物体在无限远处, R=EFL, 并且 r=EPD/2 。 插入估价等式 13.1: Except for the sign, this is the value shown in the boxed-in region under the column TSPH. ZEMAX defines TSPH = s1/ (2n ′u′), where u ′ is negative. 除了符号以外, 这个评估被显示在 boxed
