    例如zemax knowledge base的文章,连接如下:http://www.zemax.com/kb/articles/249/1/How-do-I-Account-for-Energy-Losses-When-Performing-a-Sequential-Ghost-Analysis/Page1.html dD8f`*"*=

    RMS is the RMS spot radius on axis at the primary wavelength. tZ ]/?+1G  
    RMS values of 0.00 indicate that an accurate RMS .-g++f(_i  
    could not be computed, usually due to ray errors.
    This analysis may be inaccurate if the system is z!GLug*j`

    用CODE V分析更好

    我现在好像明白一点了,可是这个结果该怎么分析呢?比如这个鬼像发生后的有效焦距8.2347,到底会对成像有多撒影响呢? ^2L\Y2

    Distance to ghost pupil: -50.9613 Distance to ghost focus到底说明了什么哦
