           最近闲的无聊,看zemax的macro 下面有个宏里自带的macro,原样附下,讨论下标记为 ****************************的作用,为什么要以渐晕为判断标准,这个渐晕的真正作用是干什么的?附下RAYV()->如果无渐晕则为0,否则为渐晕面的编号。(0 if ray was not vignetted,else vignetted surface number.valid only after a RAYTRACE or RAYTRACEEX call)。若大神赐教,小弟感激流涕············· (QTF+~)

    centroid的chief ray定義為通過光束中心(而非stop中心)的光線,其位置會受漸暈 2n,z`(=  
    的影響,因此須知道漸暈才能算出chief ray位置。
