一、概述随着光学自动设计的普遍推广和使用,光学设计人员对象差理论、象差分析等,是否就可扔到一边了?我们认为与此相反,倒是要求更高了,因为对光学系统追迹的光线更多了。一次迭代几乎把所有象差都计算一遍,因此各象差之间相互关系及制约作用暴露得更为明显。经过我们不断计算实践,现对波色差∑(d-D)dn提出一些不成熟看法。二、近似性由象差理论知道,波色差W_(FC)应为: I. Overview With the general promotion and use of optical automatic design, optical design personnel object difference theory, aberration analysis, etc., can be thrown aside? Instead, we think it touches on higher requirements, because the optical system Tracing light more. Almost all the aberrations are calculated once in an iteration, so the correlations and the constraints between the aberrations are exposed more clearly. After our constant calculations, we now present some immature opinions on the wave color difference Σ (d-D) dn. Second, the approximation by the theory of aberration, wave color deviation W_ (FC) should be:
