最佳非球面位置的确定─APS因子及其应用

The determination of optimum aspheric position──APS factor and its applications

非球面化一直是光学设计领域内非常重要但未得到充分应用的一个方面，近年来材料科学和加工工艺的发展在一定程度上促进了非球面化的实际应用。本文是作者在实际非球面化工作中经验的归纳和总结，通过引入非球面化位置选择因子（ＡＰＳ因子），对如何选择最佳非球面位置进行了系统的探讨，得出了ＡＰＳ因子与待校像差、最佳非球面位置的关系。

Aspherization has always been a very important but-not-Sufficiently-applied aspect in optical design,the current devolopment of material science and processing technology has greatly accel-erated its practical applications.This paper comes from a summary of practical aspherization example,By introduction of Aspherized Position Selecting(APS)factor.Detailed discussion is made o how to de- termine the optimum aspheric position.The relation among APS factor correcting aberrations and opti-mum aspheric position is derived.
