發(fā)現(xiàn)zemax中的近軸光線與我想的不太一樣，它原文是這么說的 mE[y SrV
To ensure these features work properly, even for optical systems that do not meet the paraxial assumption above, Zemax traces “parabasal” rays which are real (real means using Snell's law explicitly) that make small angles with respect to a reference ray, which is usually an axis or chief ray. 2an f$^[

一直不明白這個“parabasal” rays是什么，它說是基于這種光線的真實光線追跡來得到的近軸光線追跡的數(shù)據(jù) 7>RY/O;Z,
比如現(xiàn)在我的視場角是10，當光瞳坐標Px=0，Py=0的情況下（即主光線），為什么近軸光線追跡和真實光線追跡仍然有差別。
